Abstract :
A X-band 8-watt AlGaAs/InGaAs/GaAs PHEMT MMIC power amplifier for the active phase radar applications is demonstrated. This amplifier is designed to fully match 50 ohm input and output impedance. With 8 volts and 850 mA DC bias condition, 17.5 dB small-signal gain, 39.3 dBm (8.5 watt) 2-dB gain compression power with 33.7% power-added efficiency and 40 dBm (10 watt) saturation power from 9.3 to 10.4 GHz can be achieved.
