1、高周波阻止回路と直流阻止回路の影響により、動作
不安定となりやすい。1. Operation tends to become unstable due to the effects of the high frequency blocking circuit and the DC blocking circuit.
2、発振周波数から、相当能れた周波数(離調周波数)
での雑音が多い。2. Frequency significantly higher than the oscillation frequency (detuned frequency)
There is a lot of noise.
本考案は、高周波阻止回路と直流阻止回路を用いるかわ
りに高周波減衰器を用い、かつ、誘電体共振器から出力
を取出すことにより上記欠点を除去し、離調周波数での
雑音が抑圧され、安定な動作を行なう発振器を提供する
ことを目的としている。The present invention eliminates the above drawbacks by using a high frequency attenuator instead of a high frequency blocking circuit and a DC blocking circuit and extracting the output from a dielectric resonator, suppressing noise at detuned frequencies and providing stable The purpose of this invention is to provide an oscillator that performs the following operations.
すなわち、本考案は、負性抵抗素子と、誘電体共振器と

接地されない、高周波減衰器と、前記誘電体共振器に結
合した、出力線路により構成される。That is, the present invention provides a negative resistance element, a dielectric resonator, a strip line coupled to the dielectric resonator and connected to the negative resistance element, and a strip line that is in contact with the strip line and is not grounded in terms of DC. It is composed of a high frequency attenuator and an output line coupled to the dielectric resonator.
負性抵抗素子と誘電体共振器で構成される発振部は、線
路の特性インピーダンスで終端すると単一共振回路とな

圧供給のためには、直流阻止回路および高周波阻止回路
が必要であり、これらの阻止回路の付加により、単一共
振回路から外れるようになる。Since this terminating resistor is normally of the ground type, a DC blocking circuit and a high frequency blocking circuit are required to supply a DC bias voltage, and by adding these blocking circuits, it becomes possible to deviate from a single resonant circuit.

また出力は、誘電体共振器3に結合する出力ストリップ
線路8から取出されるので、この誘電体共振器6による
濾波作用のため離調周波数帯の雑音は抑圧される。Furthermore, since the output is taken out from the output strip line 8 coupled to the dielectric resonator 3, noise in the detuned frequency band is suppressed due to the filtering effect of the dielectric resonator 6.
非接地型高周波減衰器7としては、カーボニル鉄を混入
した幅lQmm、長さは短かい側が20mm、長い側が
3Q mm、厚さ1mmのゴム板を、2.2mm幅のス
トリップラインを覆うように、テプロンガラス積層板か
らなる基板2の上にねじ9を用いて固着した。The non-grounded high frequency attenuator 7 is made of a rubber plate with a width of 1Q mm, a length of 20 mm on the short side and a length of 3Q mm on the long side, and a thickness of 1 mm, which is made of carbonyl iron mixed, so as to cover a 2.2 mm wide strip line. It was fixed onto a substrate 2 made of a Tepron glass laminate using screws 9.
接着剤が使用できる基板の場合は、接着剤により固着さ

高周波減衰器7の負性抵抗素子1側の端部がテーパー付
けされているのは、もち論、線路との整合をとるためで

衰量により抑圧されるので、この付加回路による不安定
さはなくなる。FIG. 3 shows a modification of the oscillator shown in FIG. 2 so as to take out a monitoring output. In this case, the high frequency blocking circuit 4 and DC element circuit 5 in the conventional example shown in FIG. Since they are attached to the other end of the attenuator 7, the influence of these additional circuits on the oscillation section is suppressed by the amount of attenuation of the high-frequency attenuator 7, thereby eliminating instability caused by these additional circuits.

第3図の場合負性抵抗素子のバイアスは高周波阻止回路
を通して供給される。In the case of FIG. 3, the bias for the negative resistance element is supplied through a high frequency blocking circuit.
第3図の場合、監視出力側の、高周波減衰器は、テーパ
ー状の形状を威していないが、これは監視出力側のため
、線路のインピーダンス不整合があまり問題とはならな
いためであり、監視出力の線路も整合をとるためには、
高周波減衰器の形状を平行四辺形にすればよい。In the case of Fig. 3, the high-frequency attenuator on the monitoring output side does not have a tapered shape, but this is because it is on the monitoring output side, so line impedance mismatch does not pose much of a problem. In order to match the monitoring output line,
The shape of the high frequency attenuator may be a parallelogram.
第1の実施例、第2の実施例で示した、高周波減衰器の
減衰量は通常15 db組以上望ましいが、負性抵抗素
