Abstract :
A transmit-receive (T/R) switch is designed to operate at 10 GHz in a triple-well CMOS process. The transmit switch includes multiple parallel resonant networks to improve loss and isolation characteristics and the receive switch includes an impedance matching network and DC bias circuitry to increase linearity. A simple simulation model is proposed for linearity analysis of the receive switch. Finally, a figure-of-merit for T/R switches is proposed and used to compare previous published results.
