【考案の詳細な説明】
本考案は、同軸導波管変換器付マイクロ波集積回路の改
良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a microwave integrated circuit with a coaxial waveguide converter.
マイクロ波集積回路（Ｍｉｃｒｏｗａｖｅ Ｉｎｔｅｇ
ｒａｔｅｄＣｉｒｃｕｉｔ、以下ＭＩＣと称する）のマ
イクロ波入出力端子には、その構造上、同軸線路または
マイクロストリップ線路が用いられるのが一般的である
。Microwave integrated circuit
Due to its structure, a coaxial line or a microstrip line is generally used as a microwave input/output terminal of a rated circuit (hereinafter referred to as MIC).
しかし、ＭＩＣを通信機器等へ実装する場合、例えば同
軸伝送線路のみで他の周辺部品と設続可能な場合は問題
ない。However, when mounting the MIC in a communication device or the like, there is no problem if the MIC can be connected to other peripheral components using only a coaxial transmission line, for example.
しかし、導波管と接続しなければならない時は、同軸導
波管変換器が必要で、ＭＩＣに付加しなければならない
。However, when a waveguide connection is required, a coaxial waveguide converter is required and must be added to the MIC.
ところが、従来の同軸導波管変換器付ＭＩＣにおいては
、導波管の開口部フランジの向きが決まっているため、
導波管の開口部方向を変えるわずかな設計変更に対して
もＭＩＣの筐体形状の設計変更が必要とされたり、ＭＩ
Ｃに接続される周辺部品の位置の見直しが必要とされる
欠点を有していた。However, in conventional MICs with coaxial waveguide converters, the orientation of the opening flange of the waveguide is fixed;
Even a slight design change that changes the opening direction of the waveguide may require a design change to the MIC housing shape, or the MI
This had the disadvantage that the positions of peripheral parts connected to C had to be reconsidered.
これを防止する一手段として同軸導波管変換器の部分を
ＭＩＣに対し、前記プローブを軸にして回転させること
も考えられるが、構造が複雑であり、高周波特性に最も
影響のあるプローブ付近に可動部分を設けることは好ま
しくない。As a way to prevent this, it is possible to rotate the coaxial waveguide converter part with respect to the MIC around the probe, but the structure is complicated and the part near the probe that has the greatest effect on high frequency characteristics is considered. It is undesirable to have moving parts.
本考案は上記の欠点を除去するもので、同軸導波管変換
器の導波管部を貫通にして、その両端を開放にしておき

とで、ＭＩＣ及びその周辺部品の位置は何ら変更するこ
となく、１８０°反対方向へ信号を取り出せることを特
長とした同軸導波管変換器付マイクロ波集積回路を提供
することを目的とする。The present invention eliminates the above-mentioned drawbacks by penetrating the waveguide section of the coaxial waveguide converter and leaving both ends open, so that the probe to be coupled to the coaxial line is placed in the axial direction of the waveguide. By inserting the MIC into the waveguide at approximately the center, and attaching a removable metal plate to either end of both openings of the waveguide, the position of the MIC and its peripheral parts cannot be changed in any way. It is an object of the present invention to provide a microwave integrated circuit with a coaxial waveguide converter, which is characterized in that signals can be extracted in the opposite direction by 180° without any interference.
以下、本考案の一つの実施例を図面を参照して説明する
。Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
一例として図に本考案の一実施例の同軸導波管変換器付
ＭＩＣ受信部の説明図を示す。As an example, the figure shows an explanatory diagram of an MIC receiving section with a coaxial waveguide converter according to an embodiment of the present invention.

、４は導波管３の磁界面から挿入されたプローブ、５は
フランジ、６はフランジ、７は金属板、８はＭＩＣ出力
端子、９はＭＩＣバイアス端子である。In the figure, 1 is the MIC receiver, 2 is the coaxial part, 3 is the waveguide, 4 is the probe inserted from the magnetic interface of the waveguide 3, 5 is the flange, 6 is the flange, 7 is the metal plate, and 8 is the MIC The output terminal 9 is a MIC bias terminal.
ここにおいて、導波管３内のマイクロ波はプローブ４で
電界結合して同軸部２を介してＭＩＣ受信部１へ導かれ
る。Here, the microwaves within the waveguide 3 are electrically coupled by the probe 4 and guided to the MIC receiving section 1 via the coaxial section 2.
なお、１０はプローブ４の周囲をとりまいている絶縁体
である。Note that 10 is an insulator surrounding the probe 4.
図において、Ａ方向から受信したい場合は、金属板７を
フランジ６側につけ短絡面を形成する。In the figure, when receiving from direction A, a metal plate 7 is attached to the flange 6 side to form a short-circuit surface.
プローブ４と金属板７間の距離１１は公知の通り、信号
の導波管内波長λｇの約（２ｎ−１）／４（ｎ：整数）
倍に選ぶ。As is known, the distance 11 between the probe 4 and the metal plate 7 is approximately (2n-1)/4 (n: integer) of the waveguide wavelength λg of the signal.
Choose twice.
次に、Ｂ方向から受信するときは、金属板７をフランジ
５側に取り付ける。Next, when receiving from direction B, the metal plate 7 is attached to the flange 5 side.
プローブ４と金属板７間の距離１２は１１と同様λｇの
（２ｎ−１） ／４ （ｎ ：整数）倍に選ぶ。Similarly to 11, the distance 12 between the probe 4 and the metal plate 7 is selected to be (2n-1)/4 (n: integer) times λg.
したがって、導波管の全長Ｗは（２ｎ−１）λｇ／２と
なる。Therefore, the total length W of the waveguide is (2n-1)λg/2.
上記の説明の如く、いとも簡単に導波管フランジの向き
を変更できる特徴を本考案は有する。As explained above, the present invention has the feature that the direction of the waveguide flange can be changed very easily.

の構造位置は変更せずそのままの状能で１８０°反対の
向きに変更できる。As described above, according to the present invention, the orientation of the waveguide flange surface of the MIC with a coaxial waveguide converter can be changed by simply attaching and detaching the metal plate to the structure of the MIC itself and the parts connected to it. The position can be changed 180 degrees in the opposite direction without changing the position.
したがって本考案はＭＩＣ等が通信機器等に実装された
あとで１８０°導波管の開口部の向きを変更する場合に
最もその効力を発揮する。Therefore, the present invention is most effective when changing the orientation of the opening of the 180° waveguide after the MIC or the like is mounted on a communication device or the like.
