Low Insertion‐Loss High Power X‐Band SPDT Transmit/Receive Switches in 250 nm GaN HEMT

Microwave and Optical Technology Letters, Volume 68, Issue 6, June 2026.
ABSTRACT We present three X‐band transmit/receive (T/R) switches utilizing single‐pole double‐throw (SPDT) structures in 250 nm GaN HEMT technology. The first T/R switch was designed to achieve low insertion loss by constructing the SPDT structure with a series λ/4 transmission line (T‐line) and meticulously selected two HEMT switches in parallel for ...
