Abstract This paper presents the design of an S-band HPA MMIC in AlGaN/GaN CPW technology for radar TR-module application. The trade-offs of using an MMIC solution versus discrete power devices are discussed. The MMIC shows a maximum output power of 38 Watt at 37% Power Added Efficiency at 3.1 GHz. An output power of more than 20 Watt has been simulated from 2.5 to 3.7 GHz. The robustness against high output VSWR values up to 4:1 has been checked and simulations show a maximum drain-gate voltage of around 60 V.
