以下、本発明を図面に基づいて説明する。   Hereinafter, the present invention will be described with reference to the drawings.

図１〜図３は本発明に係わる方向性結合器の機能を有する導波管変換器の一実施例を示しており、図１に示すように、この導波管変換器１は、２本の導波管２，３を備えており、高周波発振器入力端１０に一端側を接続させた一方の導波管２と他方の導波管３とを互いに略直交させて接合すると共に、双方の接合面２ａ，３ａに設けた連通孔４を介して一方の導波管２と他方の導波管３とを連通させて成っている。   1 to 3 show an embodiment of a waveguide converter having the function of a directional coupler according to the present invention. As shown in FIG. And one waveguide 2 whose one end is connected to the high-frequency oscillator input end 10 and the other waveguide 3 are joined substantially orthogonally to each other. One waveguide 2 and the other waveguide 3 are communicated with each other through a communication hole 4 provided in the joint surfaces 2a and 3a.

この場合、一方の導波管２及び他方の導波管３はいずれも非金属材料から成り、両導波管２，３の各内部には金属メッキが施してあって、それぞれ同一の矩形断面を有する角管状を成している。そして、連通孔４は、正方形状を成す接合面２ａ，３ａの対角線上に位置する長孔４ａ及びこれと略直交する長孔４ｂから成る十字孔をとして形成してあり、この実施例では、接合面２ａ，３ａに２個の連通孔４，４を配置している。なお、連通孔４の個数及び大きさで結合の度合いが決定される。なお、一方の導波管２及び他方の導波管３をいずれも金属材料から成るものとしても差し支えない。   In this case, the one waveguide 2 and the other waveguide 3 are both made of a non-metallic material, and the inside of each of the waveguides 2 and 3 is metal-plated and has the same rectangular cross section. It has a rectangular tube shape. The communication hole 4 is formed as a cross hole composed of a long hole 4a located on a diagonal line of the joining surfaces 2a and 3a having a square shape and a long hole 4b substantially orthogonal thereto, and in this embodiment, Two communication holes 4 and 4 are arranged on the joint surfaces 2a and 3a. The degree of coupling is determined by the number and size of the communication holes 4. Note that both the one waveguide 2 and the other waveguide 3 may be made of a metal material.

また、高周波発振器入力端１０に一端側を接続させた一方の導波管２の他端側を湾曲状反射板５で閉塞してあり、他方の導波管３に設けた２個の端子６，７のうちの一方の端子６を基準信号入力用とすると共に、他方の端子７を隣接する高周波発振器への基準信号出力用として使用するようにしている。なお、当然のことながら、反射板５を直線状としても勿論動作する。   Further, the other end side of one waveguide 2 whose one end is connected to the high-frequency oscillator input end 10 is closed with a curved reflector 5, and two terminals 6 provided on the other waveguide 3. , 7 is used for inputting a reference signal, and the other terminal 7 is used for outputting a reference signal to an adjacent high-frequency oscillator. Needless to say, the reflector 5 operates as a straight line.

そこで、高周波発振器を高周波発振器入力端１０に接続した時の高周波発振器のフリーラン時におけるスペクトラム波形（図４に示す）と、上記導波管変換器１を用いて高周波発振器入力端１０に入力するマイクロ波に高安定な基準信号を注入した場合のスペクトラム波形（図５に示す）とを比較したところ、両図の各波形から明らかなように、この実施例における導波管変換器１を用いた基準信号の注入によって、出力波の安定化が図られていることが立証できた。   Therefore, a spectrum waveform (shown in FIG. 4) at the time of free-running of the high frequency oscillator when the high frequency oscillator is connected to the high frequency oscillator input end 10 and the waveguide converter 1 are used for input to the high frequency oscillator input end 10. When the spectrum waveform (shown in FIG. 5) when a highly stable reference signal is injected into the microwave is compared, as is apparent from the waveforms in both figures, the waveguide converter 1 in this embodiment is used. It was proved that the output wave was stabilized by the injection of the reference signal.

上記した方向性結合器の機能を有する導波管変換器１では、一方の導波管２と他方の導波管３とを互いに略直交させて接合し、双方の接合面２ａ，３ａに設けた連通孔４を介して両導波管２，３を連通させているので、高周波発振器入力端１０からの入力波の安定化を図るにあたって、機器の小型化及び重量の低減を実現することが可能である。   In the waveguide converter 1 having the function of the directional coupler described above, one waveguide 2 and the other waveguide 3 are joined so as to be substantially orthogonal to each other, and provided on both joining surfaces 2a and 3a. Since the waveguides 2 and 3 are communicated with each other through the communication hole 4, it is possible to reduce the size and weight of the device when stabilizing the input wave from the high-frequency oscillator input end 10. Is possible.

また、上記した方向性結合器の機能を有する導波管変換器１では、他方の導波管３の２個の端子６，７のうちの一方の端子６を基準信号入力用とし、他方の端子７を隣接する高周波発振器への基準信号出力用として使用するようにしているので、複数の高周波発振器の出力波を安定化させることができ、上記した導波管変換器１では、連通孔４を十字孔をとして形成しているので、高周波発振器入力端１０から入力されたマイクロ波に対する高安定な基準信号の注入を効率良く行うことができる。   In the waveguide converter 1 having the function of the directional coupler described above, one terminal 6 of the two terminals 6 and 7 of the other waveguide 3 is used for reference signal input, and the other Since the terminal 7 is used for outputting the reference signal to the adjacent high-frequency oscillator, the output waves of the plurality of high-frequency oscillators can be stabilized. In the waveguide converter 1 described above, the communication hole 4 Is formed as a cross hole, so that a highly stable reference signal can be efficiently injected into the microwave input from the high-frequency oscillator input terminal 10.

さらに、上記した導波管変換器１では、非金属材料から成る一方の導波管２及び他方の導波管３の各内部に金属メッキを施しているので、機器のより一層の軽量化を実現することが可能であり、加えて、上記した導波管変換器１では、高周波発振器入力端１０に一端側を接続させた一方の導波管２の他端側を湾曲状反射板５で閉塞しているので、通過周波数の広帯域化が可能となって、高周波発振器入力端１０に入力する信号の変動に伴う出力マイクロ波の劣化を低減することができる。   Furthermore, in the waveguide converter 1 described above, the metal plating is applied to the inside of each of the one waveguide 2 and the other waveguide 3 made of a non-metallic material. In addition, in the above-described waveguide converter 1, the other end side of one waveguide 2 whose one end side is connected to the high-frequency oscillator input end 10 is connected to the curved reflector 5. Since it is blocked, it is possible to widen the pass frequency, and it is possible to reduce the deterioration of the output microwave due to the fluctuation of the signal input to the high-frequency oscillator input terminal 10.

本発明の高周波発振器の出力波安定化方法及び導波管変換器では、機器の大型化及び重量の増加を招くことなく、高周波発振器の出力波の安定化を実現することが可能であることから、宇宙における太陽発電システムに用いたり、極地や被災地における観測機器への電力送電に用いたり、高密度プラズマ発生装置における周波数安定化回路やレーダの安定化回路に用いたりすることができる。   In the output wave stabilization method and the waveguide converter of the high frequency oscillator of the present invention, it is possible to achieve stabilization of the output wave of the high frequency oscillator without causing an increase in size and weight of the device. It can be used for solar power generation systems in space, for power transmission to observation equipment in polar regions and disaster areas, and for frequency stabilization circuits and radar stabilization circuits in high-density plasma generators.
