摘要

提出了一种在低控制电压下实现高功率、低失真工作的收发单片微波集成电路开关。由电感、电容器和开关场效应管组成的lc谐振开关被集成到TX和RX臂中，以提供反向控制方案，消除传输模式中的RF电压限制。总外径为2.88 mm的lc谐振T/R开关，当控制在0 V/2 V时，当输入功率高达28 dBm时，第三IMR小于-40 dB。

Low voltage, high power T/R switch MMIC using LC resonators

A T/R (transmit/receive) MMIC (monolithic microwave integrated circuit) switch for high-power/low-distortion operation at low control voltage is proposed. LC-resonant switches composed of inductors, capacitors, and switching FETs are incorporated in the TX and RX arms to provide a reverse control scheme which removes the RF voltage limitation in the transmit mode. An LC-resonant T/R switch with total periphery of 2.88 mm exhibits third IMR less than -40 dB for input power up to 28 dBm when controlled at 0 V/2 V.<>
