Abstract :
A compact 6 W AlGaAs/InGaAs/GaAs monolithic microwave integrated circuit (MMIC) high power amplifier (HPA) is proposed for Ku-band applications. This three-stage amplifier with layout size of 14.35 mm2 (4.39 mm×3.27 mm) is designed to fully match 50 O input and output impedance. with 8 V and 3300 mA DC bias condition, the MMIC delivers 30.4 dB small-signal gain, 37.8 dBm saturated output power with 23.4 % power added efficiency from 12 to 15 GHz. the 38.5 dBm of maximum output power with 27 % of peak power added efficiency at 13.3 GHz can be achieved. the amplifier circuit is fabricated in 0.25 μm pseudomorphic high electronic mobility transistor (pHEMT) technology.
