Abstract

A 40-110 GHz SPDT T/R switch fabricated in 90 nm CMOS is presented. The traveling wave switch is used to obtain low insertion loss and wide operating bandwidth. To enhance the isolation performance, the parallel inductor is adopted. The insertion loss is improved with body-floating. The measurement results show that the insertion loss is lower than 4 dB and isolation is better than 21 dB. A very good isolation value higher than 56 dB at 109 GHz is achieved. The chip core size is 0.11 mm2.
