GaN MMIC SPDTs for C-Ku band beam forming networks applications

Abstract

In this contribution two robust, broadband SPDTs designed in GaN MMIC technology operating in the C-Ku Band are presented. The first SPDT is an absorptive type switch featuring 1.7 dB average insertion loss and 30 dB minimum isolation. The second SPDT is a reflective type switch featuring 1 dB minimum insertion loss and 30 dB minimum isolation. Both SPDTs have the same fit form and function and can be implemented in star configuration to realize RF signal routing and distribution for analogue beam forming networks.
