摘要

提出了一种24ghz低损耗高隔离吸收型砷化镓SPDT PIN二极管开关的设计。该开关总共包含6个PIN二极管，即每个臂上有3个二极管。其中两个二极管用于高隔离目的，第三个二极管为隔离端口提供匹配的负载。在22 ~ 26 GHz频段，测量到的插入损耗和隔离度分别优于1.4 dB和47 dB。在同一频段内，输入输出回波损耗均优于12db

A low-loss high-isolation absorptive GaAs SPDT PIN switch for 24 GHz automotive applications

Design of a low-loss high-isolation absorptive GaAs SPDT PIN diode switch at 24 GHz is presented. The switch incorporates a total of 6 PIN diodes, i.e., 3 diodes in each arm. Two of the diodes are for high isolation purposes and the third diode provides the matched load to the isolated port. The measured insertion loss and isolation are better than 1.4 dB and 47 dB, respectively, in the frequency band 22 to 26 GHz. The input and output return losses are better than 12 dB in the same frequency band
