絶縁耐力を向上させるには、この間の距離を大きくして
いた。Conventionally, this type of high power circulator has a space between the outer conductor and inner conductor of the triplate, and in order to improve the dielectric strength of this part, the distance between them has been increased.
上述した従来の高電力用サーキュレータは、トリプレー
トの内外導体間の距離を大きくする必要があることから
、大型になる欠点がある。The conventional high-power circulator described above has the disadvantage of being large because it is necessary to increase the distance between the inner and outer conductors of the triplate.

いる。Particularly in the case of high-power circulators for satellites, for example, for satellite-mounted synthetic aperture radars, the peak value of output power is 2.
kW or more, and the high-power circulator used in the transmitter is required to be small and lightweight for use onboard a satellite. (approximately 3 kV/gu+)
Therefore, the above-mentioned drawbacks have become a big problem.

れている。A dielectric 6 made of Teflon (trade name of DuPont, USA), which is a polymer of tetrafluoroethylene, has a depression on the outer conductor 8 side, and this depression is filled with a dielectric 9 without any gaps. . The space between the inner conductor 1 and the outer conductor 8 constituting the triplate is filled with dielectrics 6 and 9 without any gaps.

きる効果がある。As explained above, in the present invention, by filling the space between the inner conductor and the outer conductor of a circulator with a tri-plate structure with the first dielectric material such as Teflon, which has a high dielectric strength, it is possible to significantly improve the power resistance. In addition, sufficient power resistance can be obtained even if the distance between the outer conductor and the inner conductor is short, so there is an effect of miniaturization.
