Abstract
Monolithic GaAs FET power amplifiers consisting of several power combined devices have been fabricated and evaluated. The baseline monolithic chip design consists of a single-stage 640- mu m monolithic FET amplifier. This monolithic chip has 6 dB of small signal gain and 23.5 dBm of saturated power at 50 GHz. Several such chips were power combined and cascaded to produce a five-stage amplifier that yields 28 dBm of saturated power with 18 dB of gain from 48 to 52 GHz.<>
