Abstract :
A miniature power amplifier, which combines two conventional distributed amplifiers and a single transistor amplifier is designed to achieve wide bandwidth, high gain and moderate output power from 15 to 50 GHz. This circuit was fabricated using 0.15-mum GaAs based pHEMT MMIC technology. The measured small signal gain is 21plusmn1.5dB from 15 to 50 GHz, and the output saturated power is 18-22 dBm from 18 to 50 GHz with a miniature size of 1.5 times 1 mm2
