摘要

设计了一种采用0.5um GaAs PHEMT工艺的单片微波集成电路(MMIC) 4X2开关矩阵，用于0.5-3GHZ应用。该开关矩阵由四个特殊的SPDT开关和一个集成在单个芯片上的4位逻辑解码器组成。还考虑了感应键合线和封装寄生效应。该开关矩阵被设计为由正电压控制。所设计的开关矩阵在所有工作条件下均表现出良好的性能:插入损耗小于5dB，隔离度不小于30dB，回波损耗优于-12dB, P1dB优于26dBm。设计的开关矩阵芯片尺寸仅为1.45mm*1.45mm。

A MMIC 4X2 switch matrix for 0.5–3GHZ application

A Monolithic microwave integrated circuit (MMIC) 4X2 switch matrix using 0.5um GaAs PHEMT process has been designed for 0.5-3GHZ application. This switch matrix is composed of four special SPDT switches and a 4-bit logical decoder integrated on a single chip. Inductive Bonding wire and package parasite effect are also taken into consideration. This switch matrix is designed to be controlled by positive voltage. The designed switch matrix shows good performance under all working conditions: the insertion loss is less than 5dB, the isolation is no worse than 30dB, the return loss is better than -12dB, the P1dB is better than 26dBm. The chip size of designed switch matrix is only 1.45mm*1.45mm.
