Abstract	Fully integrated 0.18-µm CMOS dual-band band-pass filtering transmit/receive (T/R) switch operating in two frequency bands of 35.5–43.7 and 56.5–63 GHz is reported. The developed T/R switch consists of three single-pole double-throw switches, each designed based on a band-pass filter with shunt nMOS transistors performing the switching function. The measured insertion losses of the switch are 8.9/12.5 and 10/12.7 dB for receiving and transmitting operations at 40/60 GHz, respectively. The measured stop-band rejection ratio between 40 and 51 GHz is over 30/22 dB for two operations, respectively. The measured isolation is 56/51 and 57/51 dB for two operations at 40/60 GHz, respectively. The measured input 1-dB compression points of the switch are 23, 16.5 for single-tone 40-, 60-GHz input signal and 18/14 dBm at 40/60 GHz for concurrent dual-tone 40/60-GHz input signals for transmitting operation, respectively. The total chip size is 1840 µm × 860 µm excluding all the testing pads.
