摘要：

A transmitter/receiver (T/R) Switch in radio frequency front-end for 3.1 similar to 10.6 GHz ultra-wideband Systems is presented. The design focuses on the techniques to increase both power handling capability and isolation using deep n-well and floating bulk technology. The proposed switch achieves P1dB of 9 dBm and IIP3 of 20 dBm in transmitting (TX) mode which represents higher linearity than other CMOS T/R switches. The proposed T/R switch provides the TX and receiving (RX) paths with different switching topologies. Different signal paths can minimize the power leakage into the RX/TX path during TX/RX mode selection so as to improve the linearity. The proposed T/R switch uses a 1.8 V digital control signal for TX/RX mode selection. The simulated insertion loss is less than 2.3 dB and return loss is less than 10 dB during 3.1 similar to 10.6 GHz full-band operation.
