Abstract

This paper introduces the use of a pass-gate switch configuration to design and implement a 25-to-40 GHz single-pole double-throw (SPDT) switch in 130 nm BiCMOS technology. Also, biasing pass-gate transistor terminals to 0 V through 20 \mathbfKØmega resistance is introduced to minimize the variation in device parasitics. Performance improvements due to these design techniques have been benchmarked in the EM simulation of the proposed pass-gate switch configuration based differential SPDT switch. This SPDT switch has demonstrated minimum insertion-loss of 1.29 dB, maximum isolation of 41.2 dB and \mathbfS₁₁/\mathbfS₂₂ better than 12 dB across the frequency band of operation. This SPDT switch has also shown input PldB (IP1dB) of 15.4 dBm with a layout area of 0.11 mm2 © 2022 IEEE.
