For this reason, in order to realize an amplifier with higher output, a method of arranging a plurality of unit amplifiers in parallel and synthesizing outputs of these unit amplifiers is generally used.

特開２００１−２４４７１１号公報(第1図)JP 2001-244711 A (FIG. 1)

特に衛星搭載用高出力増幅器には底面積が小さいことが要求されている。しかしながら、従来の高出力増幅器は単位増幅器、分配器及び合成器とが同一平面上に形成されており、しかも合成器の低損失化を図るため方形同軸線路や導波管で形成した合成器を用いる場合はさらに高出力増幅器の底面積が大きくなってしまう課題があった。   In particular, high-power amplifiers for satellite use are required to have a small bottom area. However, in the conventional high-power amplifier, the unit amplifier, the divider and the combiner are formed on the same plane, and in order to reduce the loss of the combiner, a combiner formed of a rectangular coaxial line or a waveguide is used. When used, there is a problem that the bottom area of the high-power amplifier is further increased.

An input terminal consisting of a coaxial line, a connection terminal is attached to the hole, the input terminal and the distributor are connected, the unit amplifier and the connection terminal are connected by a metal ribbon, etc., and the combiner is an outer conductor, its It consists of an inner conductor, an output terminal, a terminator and a synthesizer cover arranged inside, and the inner conductor and the terminator are connected by a metal ribbon or the like, the inner conductor and the connection terminal, the inner conductor and the output terminal Is the above inner conductor Those connected after insertion so as to be perpendicular to the drilled part bore.

この発明は、増幅部の隣に合成器を直角に立てて配置し、増幅部と合成器とを接続端子を介して電気的に接続した構成のものであり、増幅部は増幅器シャーシ内に配置した１個の分配器と２個の単位増幅器、増幅部カバーからなり、合成器は外導体と、その内部に配置した内導体、出力端子、終端器及び合成器カバーからなることにより、大きな底面積をしめる合成器を増幅部に対して直角方向に設けることで合成器の底面積は分配器と同等の大きさにでき、高出力増幅器の底面積を小さくすることができるという効果がある。   The present invention has a configuration in which a synthesizer is arranged at a right angle next to an amplifying unit, and the amplifying unit and the synthesizer are electrically connected via a connection terminal. The amplifying unit is arranged in an amplifier chassis. 1 distributor, 2 unit amplifiers, and amplifying unit cover. The combiner consists of an outer conductor, an inner conductor, an output terminal, a terminator, and a combiner cover arranged inside.

実施の形態１．
図１、図２はこの発明の実施の形態１における高出力増幅器の斜視図である。図１は組立状態の斜視図、図２は分解した状態での上方斜視図である。この高出力増幅器は増幅部１の隣に合成器２を直角に立てて配置し、増幅部１と合成器２とは接続端子７を介して電気的に接続した構成のものである。 Embodiment 1 FIG.
1 and 2 are perspective views of a high-power amplifier according to Embodiment 1 of the present invention. FIG. 1 is a perspective view in an assembled state, and FIG. 2 is an upper perspective view in an exploded state. This high-power amplifier has a configuration in which a synthesizer 2 is arranged at a right angle next to the amplifying unit 1, and the amplifying unit 1 and the synthesizer 2 are electrically connected via a connection terminal 7.

増幅部１は増幅器シャーシ３と、その増幅器シャーシ３内に配置した１個の分配器５と２個の単位増幅器６からなり、これらの単位増幅器６は並べて配置している。また、増幅器シャーシ３の側面には側面を貫通する穴が設けられており、この穴には同軸線路などからなる入力端子４、接続端子７が取り付けられている。さらに入力端子４と分配器５間、単位増幅器６と接続端子７はそれぞれ金属リボン等で接続し、増幅器シャーシ３の上面にはネジでカバー８が取り付けられている。   The amplifying unit 1 includes an amplifier chassis 3, one distributor 5 and two unit amplifiers 6 arranged in the amplifier chassis 3, and these unit amplifiers 6 are arranged side by side. Further, a hole penetrating the side surface is provided on the side surface of the amplifier chassis 3, and an input terminal 4 and a connection terminal 7 made of a coaxial line or the like are attached to the hole. Further, the input terminal 4 and the distributor 5, the unit amplifier 6 and the connection terminal 7 are connected by a metal ribbon or the like, and a cover 8 is attached to the upper surface of the amplifier chassis 3 with screws.

合成器２は外導体９と、その内部に配置した内導体１０、出力端子１１、終端器１２及び合成器カバー１３とからなり、内導体１０と終端器１２とは金属リボン等で接続されている。内導体１０と接続端子７、内導体１０と出力端子１１とは図３のように内導体１０の一部にあけられた穴にこれらの接続端子７及び出力端子１１がそれぞれ内導体１０に対して垂直になるように挿入されており、お互いを半田付けすることにより接続されている。すなわち、内導体１０と接続端子７間、内導体１０と出力端子１１間との接続部には垂直給電部を採用している。
この内導体１０と接続端子７、内導体１０と出力端子１１の接続部においてはインピーダンス整合を考慮した設計になっており、インピーダンス不整合による損失が最小になるようになっている。更に外導体９の側面にはネジ等で合成器カバー１３が取り付けられている。 The synthesizer 2 includes an outer conductor 9, an inner conductor 10, an output terminal 11, a terminator 12, and a synthesizer cover 13 disposed therein. The inner conductor 10 and the terminator 12 are connected by a metal ribbon or the like. Yes. The inner conductor 10 and the connection terminal 7, and the inner conductor 10 and the output terminal 11 are formed in holes formed in a part of the inner conductor 10 as shown in FIG. They are inserted so as to be vertical, and are connected by soldering each other. That is, a vertical power feeding unit is employed between the inner conductor 10 and the connection terminal 7 and between the inner conductor 10 and the output terminal 11.
The connection portion between the inner conductor 10 and the connection terminal 7 and the connection portion between the inner conductor 10 and the output terminal 11 is designed in consideration of impedance matching, and the loss due to impedance mismatch is minimized. Further, a synthesizer cover 13 is attached to the side surface of the outer conductor 9 with screws or the like.

このような構造になっているため内導体１０、外導体９、合成器カバー１３とからなる方形同軸線路形のハイブリッドとして機能するような設計になっている。   Since it has such a structure, it is designed to function as a rectangular coaxial line type hybrid comprising the inner conductor 10, the outer conductor 9, and the combiner cover 13.

次にこの実施の形態１に係る高出力増幅器の動作について、図面を参照しながら説明する。     Next, the operation of the high output amplifier according to the first embodiment will be described with reference to the drawings.

入力端子４から入力された信号は分配器５によって分配され、それぞれ単位増幅器６に入力される。単位増幅器６に入力された信号は単位増幅器６でそれぞれ信号が増幅され、また、それぞれの単位増幅器６から出力された信号は接続端子７を介して内導体１０の各端子に入力される。   A signal input from the input terminal 4 is distributed by the distributor 5 and input to the unit amplifier 6. The signal input to the unit amplifier 6 is amplified by the unit amplifier 6, and the signal output from each unit amplifier 6 is input to each terminal of the inner conductor 10 via the connection terminal 7.

更に接続端子７を介して内導体１０に入力されたそれぞれの信号は内導体１０と外導体９と分配器カバー１３で構成される方形同軸線路形の合成器２によって電力合成され、合成された信号は出力端子１１を介して出力される。   Further, each signal input to the inner conductor 10 via the connection terminal 7 is synthesized by the power by the rectangular coaxial line type synthesizer 2 composed of the inner conductor 10, the outer conductor 9, and the distributor cover 13. The signal is output via the output terminal 11.

以上のようにこの発明の高出力増幅器では接続端子７と内導体１０間の接続部には垂直給電部を用いることにより、電気性能を損なうことなく増幅部１と合成器２を互いに直角に配置することが可能となる。   As described above, in the high-power amplifier according to the present invention, the amplifying unit 1 and the combiner 2 are arranged at right angles to each other without impairing the electrical performance by using the vertical feeding portion for the connecting portion between the connecting terminal 7 and the inner conductor 10. It becomes possible to do.

この実施例の合成器２は低損失化の為、方形同軸線路を用いているが、出力端子１１側の表面積の大きさに比べてそれと垂直をなす側面積は小さいため、合成器２の方向を増幅部１に対して直角に配置することで合成器２の底面積を分配器５と同等の大きさに削減できる。なお、合成器２の方向を変えることによる電気性能の違いはない。   The synthesizer 2 of this embodiment uses a rectangular coaxial line to reduce the loss, but the side area perpendicular to the surface area on the output terminal 11 side is small, so the direction of the synthesizer 2 Is arranged at right angles to the amplifying unit 1, the bottom area of the synthesizer 2 can be reduced to the same size as the distributor 5. Note that there is no difference in electrical performance by changing the direction of the combiner 2.

このように大きな底面積をしめる合成器２を増幅部１に対して直角方向に設けることで合成器２の底面積は分配器５と同等の大きさにでき、高出力増幅器の底面積が小さくなるという効果がある。   By providing the synthesizer 2 having such a large bottom area in a direction perpendicular to the amplifying unit 1, the bottom area of the synthesizer 2 can be made the same size as the distributor 5, and the bottom area of the high-power amplifier is small. There is an effect of becoming.

更に、増幅部１と合成器２を別々に組み立てることが可能であるため、組み立て作業が容易になるという効果がある。   Furthermore, since the amplifying unit 1 and the combiner 2 can be assembled separately, there is an effect that the assembling work becomes easy.

さらに単位増幅器６からの出力が接続端子７を介してそれぞれ出力されているため、単位増幅器６それぞれの電気特性の確認が容易になる効果がある。   Furthermore, since the outputs from the unit amplifiers 6 are respectively output via the connection terminals 7, there is an effect that it is easy to confirm the electrical characteristics of each unit amplifier 6.

また、合成器２は図２に示すような方形同軸線路で実現する他にマイクロストリップ線路、ストリップ線路、導波管回路で構成しても同じように実現可能である。この場合、方形同軸線路に対して、合成器２のさらなる小型化や耐電力性能の向上を得ることができる効果がある。   Further, the synthesizer 2 can be realized in the same manner by being constituted by a microstrip line, a strip line, and a waveguide circuit in addition to being realized by a rectangular coaxial line as shown in FIG. In this case, there is an effect that the synthesizer 2 can be further reduced in size and improved in power durability with respect to the rectangular coaxial line.

また、図４に示すように内導体１０と接続端子７、内導体１０と出力端子１１の接続は、半田付けによる接続の他に、インピーダンス整合をとりインピーダンス不整合による損失が最小となるように金属リボン１４で接続しても同じように実現可能である。この図では内導体１０と出力端子１１の接続を示しているが、内導体１０と接続端子７の接続についても同様である。
この場合は図３の接続方法に比べ、金属リボン１４が振動、衝撃に対してストレスリリーフの役割をするために振動、衝撃に強くなるという効果がある。 Further, as shown in FIG. 4, the connection between the inner conductor 10 and the connection terminal 7 and the connection between the inner conductor 10 and the output terminal 11 are performed by impedance matching so that the loss due to impedance mismatch is minimized in addition to the connection by soldering. Even if it connects with the metal ribbon 14, it is realizable similarly. Although the connection between the inner conductor 10 and the output terminal 11 is shown in this drawing, the same applies to the connection between the inner conductor 10 and the connection terminal 7.
In this case, compared to the connection method of FIG. 3, the metal ribbon 14 plays a role of stress relief against vibration and impact, so that it has an effect of being strong against vibration and impact.

さらに図５に示すように内導体１０の一部を垂直方向に曲げ、この部分を出力端子１１として使用することにより出力端子１１と内導体１０を一体形成することが可能で、図３に示すように内導体１０と出力端子１１とを個別に製作し、これらを半田付けで接続する方法とほぼ同じ機能を持たせることが可能である。   Further, as shown in FIG. 5, it is possible to integrally form the output terminal 11 and the inner conductor 10 by bending a part of the inner conductor 10 in the vertical direction and using this part as the output terminal 11, as shown in FIG. As described above, the inner conductor 10 and the output terminal 11 can be individually manufactured and can have substantially the same function as a method of connecting them by soldering.

なお、この図では内導体１０と出力端子１１の接続を示しているが、内導体１０と接続端子７の接続についても同様である。このため、図３の場合に比べ、部品点数が少なくなる効果がある。   Although the connection between the inner conductor 10 and the output terminal 11 is shown in this figure, the same applies to the connection between the inner conductor 10 and the connection terminal 7. For this reason, compared with the case of FIG. 3, there is an effect that the number of parts is reduced.

実施の形態２．
図６は実施の形態２における高出力増幅器の分解した状態で斜視図である。増幅部１については実施の形態１と同じであるが、合成器２と増幅部１とのその接続には直角に曲げたケーブル１５でを用いる点が実施の形態１と異なる。 Embodiment 2. FIG.
FIG. 6 is an exploded perspective view of the high-power amplifier according to the second embodiment. The amplifying unit 1 is the same as that of the first embodiment, but is different from the first embodiment in that a cable 15 bent at a right angle is used for the connection between the combiner 2 and the amplifying unit 1.

ここで使用する合成器２の基本的な構成は図２と同じであるが、図２のものでは合成器２と増幅部１とを接続する接続端子７は合成器２に対して垂直方向に設けられているのに対し、この発明のものでは合成器２と増幅部１とを接続する合成器入力端子１６は同一面上に設けている点が異なる。   The basic configuration of the synthesizer 2 used here is the same as that in FIG. 2, but in the case of FIG. 2, the connection terminal 7 that connects the synthesizer 2 and the amplifying unit 1 is perpendicular to the synthesizer 2. In contrast to the above, the present invention is different in that the synthesizer input terminal 16 for connecting the synthesizer 2 and the amplifying unit 1 is provided on the same plane.

内導体１０と合成器入力端子１６とは図７に示すようにこれらは同一平面上になるように半田付けにより接続されている。このような接続においても接続部でのインピーダンス不整合による損失を低減するように設計されている。   As shown in FIG. 7, the inner conductor 10 and the combiner input terminal 16 are connected by soldering so that they are on the same plane. Even in such a connection, it is designed to reduce a loss due to impedance mismatch at the connection portion.

従って、この実施の形態２のように直角に曲げたケーブル１５を用いることにより 実施の形態１と同じように増幅部１に対して合成器２を直角に配置することが可能である。   Therefore, by using the cable 15 bent at a right angle as in the second embodiment, the synthesizer 2 can be arranged at a right angle with respect to the amplifying unit 1 as in the first embodiment.

次にこの実施の形態２に係る高出力増幅器の動作について、図面を参照しながら説明する。     Next, the operation of the high-power amplifier according to the second embodiment will be described with reference to the drawings.

ここで示した増幅部１は実施の形態１と同じ機能を有しており、増幅部１で各接続端子７から出力された信号は直角に曲げられたケーブル１５、合成器入力端子１６を介して合成器２に入力される。さらに合成器２で電力合成され、合成された信号は出力端子１１を介して出力される。   The amplifying unit 1 shown here has the same function as that of the first embodiment, and a signal output from each connection terminal 7 in the amplifying unit 1 passes through a cable 15 bent at a right angle and a synthesizer input terminal 16. To the synthesizer 2. Further, the power is combined by the combiner 2, and the combined signal is output via the output terminal 11.

以上のように実施の形態２においても高出力増幅器の電気性能を劣化させることなく、合成器２を垂直に配置することができ、高出力増幅器の底面積を小さくすることが可能となる。なお、実施の形態１では増幅部１の接続端子７と合成器入力端子１６とを１個の接続端子７で併用する構成になっているため、それぞれの電気性能を把握する事が難しかったが、実施の形態２では合成器入力端子１６を設けているため、増幅部１と合成器２の電気特性をそれぞれ別々に確認できる効果がある。   As described above, also in Embodiment 2, the synthesizer 2 can be arranged vertically without degrading the electrical performance of the high-power amplifier, and the bottom area of the high-power amplifier can be reduced. In the first embodiment, since the connection terminal 7 of the amplifying unit 1 and the combiner input terminal 16 are configured to be used together by one connection terminal 7, it is difficult to grasp each electrical performance. In the second embodiment, since the synthesizer input terminal 16 is provided, there is an effect that the electric characteristics of the amplifying unit 1 and the synthesizer 2 can be confirmed separately.

なお、内導体１０と合成器入力端子１６との接続は図８に示すように金属リボン１４で接続することにより図７と同様の効果が得られ、金属リボン１４が振動、衝撃に対してストレスリリーフの役割をするために図７の接続方法に比べ、振動、衝撃に強くなるという効果がある。   The connection between the inner conductor 10 and the synthesizer input terminal 16 can be achieved by connecting the metal ribbon 14 with a metal ribbon 14 as shown in FIG. In order to act as a relief, there is an effect that it is stronger against vibration and impact than the connection method of FIG.

また、合成器入力端子１６は図９に示すように内導体１０と一体形成しても図７と同様の効果を得られる。
この場合、内導体１０の一体形成のため、合成器入力端子１６と内導体１０の組立作業が不要になる効果がある。 Further, even if the synthesizer input terminal 16 is formed integrally with the inner conductor 10 as shown in FIG. 9, the same effect as in FIG. 7 can be obtained.
In this case, since the inner conductor 10 is integrally formed, there is an effect that the assembling work of the synthesizer input terminal 16 and the inner conductor 10 becomes unnecessary.

なお、この実施の形態２では方形同軸線路で形成した合成器２を用いた場合について説明したが、マイクロストリップ線路やストリップ線路で形成した場合であっても同じである。   In the second embodiment, the case where the synthesizer 2 formed of a rectangular coaxial line is used has been described, but the same applies to the case where the synthesizer 2 is formed of a microstrip line or a strip line.

実施の形態３．
図１０は実施の形態３の高出力増幅器の分離した状態での下方斜視図であり、図１１は実施の形態３の分離した状態での上方斜視図である。合成器２は実施の形態２と同じ構成である。 Embodiment 3 FIG.
FIG. 10 is a lower perspective view of the high-power amplifier according to the third embodiment in a separated state, and FIG. 11 is an upper perspective view of the third embodiment in a separated state. The synthesizer 2 has the same configuration as that of the second embodiment.

増幅部１の基本的な構成は図２と同じであるが図２では増幅部１に接続端子７を設けてあったが、本発明では接続端子７が設けられていない点と、図２のカバー８にはネジ止め用の穴のみ設けてあったのに対し、本発明ではカバー８に合成器入力端子１６と貫通するための、合成器入力端子１６の外形より大きな穴を追加して設けている点が異なる。   The basic configuration of the amplifying unit 1 is the same as that of FIG. 2, but in FIG. 2, the amplifying unit 1 is provided with the connection terminal 7. However, in the present invention, the connection terminal 7 is not provided. In the present invention, only a hole for screwing is provided in the cover 8, but in the present invention, a hole larger than the outer shape of the synthesizer input terminal 16 is provided in the cover 8 so as to penetrate the synthesizer input terminal 16. Is different.

また、増幅部１と合成器２の配置は図２では増幅部１の隣に合成器２を直角に配置しているが、本発明では合成器入力端子１６がカバー８に追加した穴を貫通するように増幅部１の上に合成器２を直角配置している点が異なる。   Further, in FIG. 2, the amplifying unit 1 and the synthesizer 2 are arranged at a right angle next to the amplifying unit 1, but in the present invention, the synthesizer input terminal 16 passes through the hole added to the cover 8. The difference is that the combiner 2 is arranged at a right angle on the amplifier 1.

カバー８を通した合成器入力端子１６と増幅部１内の単位増幅器６の出力はインピーダンス整合を考慮して設計されており、インピーダンス不整合による損失が最小となるように接続する。接続後、カバー８をネジ等で増幅器シャーシ３に固定する。   The combiner input terminal 16 through the cover 8 and the output of the unit amplifier 6 in the amplifying unit 1 are designed in consideration of impedance matching, and are connected so as to minimize loss due to impedance mismatch. After the connection, the cover 8 is fixed to the amplifier chassis 3 with screws or the like.

次にこの実施の形態３に係る高出力増幅器の動作について、図面を参照しながら説明する。   Next, the operation of the high-power amplifier according to the third embodiment will be described with reference to the drawings.

入力端子４から入力された信号は分配器５によって分配され、分配された信号がそれぞれ単位増幅器６に入力される。それぞれの単位増幅器６により信号が増幅され、単位増幅器６から出力される。ここまでは実施の形態１と同じである。単位増幅器６から出力された信号は電気的に接続された合成器入力端子１６を介して合成器２に信号が入力される。合成器２で信号が電力合成され、合成された信号が出力端子１１から出力される。   A signal input from the input terminal 4 is distributed by the distributor 5, and each distributed signal is input to the unit amplifier 6. A signal is amplified by each unit amplifier 6 and output from the unit amplifier 6. The steps so far are the same as those in the first embodiment. The signal output from the unit amplifier 6 is input to the synthesizer 2 via an electrically connected synthesizer input terminal 16. The signal is synthesized by the synthesizer 2 and the synthesized signal is output from the output terminal 11.

実施の形態１では増幅部１の隣に合成器２を配置しているが、本発明については増幅部１の上に合成器２を配置する。このため実施の形態１より合成器２の底面積の分だけ更に高出力増幅器の底面積が小さくなる効果がある。   In the first embodiment, the synthesizer 2 is arranged next to the amplifying unit 1. However, the synthesizer 2 is arranged on the amplifying unit 1 in the present invention. Therefore, the bottom area of the high-power amplifier is further reduced by the amount corresponding to the bottom area of the synthesizer 2 than in the first embodiment.
