An integrated circuit of quad-band GSM single pole six thru (SP6T) switch is designed with an InGaAs/GaAs PHEMT technology. It had successfully demonstrated as play for all quad-band operations (GSM850, EGSM900, DCS1800, PCS1900). Both requirements of low insertion loss (less than 1 dB) and high isolation are achieved at the same time. Some of termination methods were used to improve the isolation between Tx and Rx.
