The highest performance to date of any switch using a CMOS process, of a 0.8dB insertion-loss, 23dB isolation and 17.4dBm power-handling capability at 5GHz, is accomplished with an optimized single-pole double-throw (SPDT) transmit/receive (T/R) switch using Depletion-layer-Extended Transistors (DETs) in a 0.18μm CMOS process. The effects of junction capacitance decrease and substrate resistance increase in the DET, the adoption of low-loss shielded-pads, and several layout optimizations, lead to the realization of this low insertion-loss. Moreover, the combined effect of the adoption of the source/drain DC biasing scheme and the high substrate resistance in the DET contributes to the high power-handling capability.
