Abstract

This paper mainly introduces a DC~18GHz wideband SPDT switch . Firstly, every possible configuration is contrasted, the theories of basic GaAs switch configurations are mentioned. Secondly, the theories of basic GaAs switch configurations are mentioned. Subsequently, appropriate topology is selected for this SPDT switch. This switch has been realized by 0.2µm GaAs PHEMT process. this switch exhibits high performance: over DC~18GHz, insertion loss is lower than 2.4dB; The isolation is lower than 45dB; the ripple variation of insertion loss is less than 1.4dB; input return loss is lower than 12dB; on state, output return loss is lower than 13dB; off state, output return loss is lower than 25dB; on and off time are less than 20ns.
