摘要

设计了毫米波回旋管行波放大器的输入耦合器。构造了一个由t型结和宽带反射器组成的w波段输入耦合器，并在w波段进行了测量。它实现了−2.2 dB的传输系数，包括丸盒窗和波导弯曲。设计并仿真了一种372 GHz的多孔耦合器。在不考虑欧姆损耗的情况下，在模拟中，372GHz耦合器的传输系数为- 0.5 dB。

Input coupling systems for mm-wave amplifiers

Input couplers for mm-wave gyrotron traveling wave amplifiers (gyro-TWAs) were designed. A W-band input coupler composed of a T-junction and a broadband reflector was constructed and measured in W-band. It achieved a transmission coefficient of −2.2 dB including the pillbox window and a waveguide bend. A multiple-hole coupler was designed and simulated at 372 GHz. Without considering the Ohmic loss, in simulations the 372GHz coupler achieved a transmission coefficient of −0.5 dB.
