  • Abstract
    In this work, an analytical approach to the design of high isolation dual-gate GaN-HEMT single-pole double-throw (SPDT) switches is presented. An R-C-R circuit is used as a band-rejection filter at the specified frequency in the OFF-state in order to realize the high isolation performance. Simulated performance of a complete SPDT using the proposed approach is presented. From DC to 3 GHz, the simulated isolation is 10 dB higher than the case without R-C-R circuit type, demonstrating the approach feasibility and effectiveness.
