开发了一种用作电子回旋电流驱动系统的高功率毫米波快速开关器件的双工器。该装置的工作频率可通过使用精密冷却器控制腔体的热膨胀来调节。在 170 GHz 频段，双工器的可调范围约为 225 MHz。环形谐振器双工器中谐振频移的温度依赖性为 -3.4 至 -3.9 MHz/K，这与理论预测一致。确认开关操作的射频功率高达 260 kW、脉冲持续时间为 100 ms、频率为 170 GHz。
A diplexer to be used as a fast switching device of high power millimeter wave for an electron cyclotron current drive system has been developed. The operation frequency of the device is tunable by controlling the thermal expansion of the cavity using a precision chiller. The tunable range of the diplexer is about 225 MHz at the frequency band of 170 GHz. The temperature dependence of the resonant frequency shift in the ring resonator diplexer is −3.4 to −3.9 MHz/K, which agrees with the theoretical prediction. The switching operation is confirmed up to rf power of 260 kW, a pulse duration of 100 ms, and a frequency of 170 GHz.
