摘要
This contribution describes the design, realization, and test of a compact X-band GaN MMIC high power amplifier (HPA) for synthetic aperture radar. The HPA represents the first step toward the realization of a fully integrated GaN transmitter/receiver (Tx/Rx) for X-band applications. The circuit is designed in a two stage configuration and it is fully matched to 50 input and output impedance. The chip area is less than 10 mm. Experimental results show an output power close to 42 dBm with a gain of 16 dB (at 3 dB of compression) and a ripple lower than 0.5 dB from 8.6 to 10.6 GHz frequency range.
