Progress In Electromagnetics Research Letters, Vol. 66, 99-104, 2017
Abstract
A novel asymmetrical single-pole double-throw (SPDT) switch for 2.4 GHz application with high power handle ability is developed. The novel asymmetrical topology is discussed. To increase the power capacity, ac-floating and dc-bias techniques are used. Using these techniques, a switch achieves a measured P1 dB of 20.5 dBm, an insertion loss (IL) of 1.16 dB and isolation loss of 20.8 dB in TX mode; an insertion loss of 1.57 dB and an isolation of 21.6 dB in RX mode. The circuit is fabricated using 3.3-V 0.35-μm DNW NMOS transistors in 0.18-μm bulk CMOS process.
