Abstract :
The development of a MMIC HPA designed for X-band radar applications is reported. The chip was fabricated with a low-cost 0.4 mum GaAs PHEMT process and is composed of two stages, with a final stage of 16 mm gate-width periphery. In the frequency bandwidth 8.5-11 GHz, the HPA delivers an output power of 8 W @ 3dB compression point, with an associated PAE of circa 30%.
