采用0.1µm pHEMTS的GaAs MMIC设计用于实现用于时间调制阵列（TMA）的增益和相位开关模块，用于73 GHz的发射或接收。作为MMIC设计的一部分，介绍了一种实现相位反转开关的新技术-无论相位开关状态如何，都能保持良好的输入输出射频匹配。给出了16个模具的实验室测量结果。在73 GHz时，测试的mmic的模拟平均增益在1.1 dB以内，相位反转切换在180度要求的3度以内。
A GaAs MMIC using 0.1 µm pHEMTS is designed to realize a gain & phase switching module for use in a Time-Modulated Array (TMA) for transmit or receive at 73 GHz. As part of the MMIC design, a novel technique to implement phase inversion switching is introduced- maintaining good input and output RF match regardless of phase switch state. Lab measured results for 16 dies are presented. At 73 GHz the tested MMICs have an average gain within 1.1 dB of simulation and phase inversion switching within 3 degrees of a 180 degree requirement.
