This paper presents the results obtained on X-Band GaN MMICs developed in the frame of the Korrigan project launched by the European Defense Agency. GaN has already demonstrated excellent output power levels, nevertheless demonstration of excellent PAE associated to very high power in MMIC technology is still challenging. In this work, we present State-of-the-Art results on AlGaN/GaN MMIC amplifiers...
A monolithic two stages high power, high efficiency and high robustness amplifier was developed for X-band applications. The combination of the improvement of the UMS HBT process called HB20P (GalnP/GaAs) in term of breakdown, the consideration of mismatch and overdrive stability in the design. The MMIC HPA which includes a bias control circuit and a TTL interface in a surface of 18.4 mm2 provides...
HBT power technology offers an excellent compromise for high power and high efficiency amplifiers up to the Ku band. In order to reduce cost and size of THALES T/R modules, we developed compact high power MMIC amplifiers with innovative transistor designs in X-band. In this paper, we present the performances of two GaInP/GaAs MMIC power amplifiers. The first one delivers an output power of 11.2W with...
