Abstract
Design approach and performance of a broadband MMIC power amplifier using cascaded single stage distributed amplifier (CSSDA) configuration are presented. CSSDA is a new topology used in broadband amplifier, which has the performance of low VSWR, high gain and facility to cascade over wide frequency band. The MMIC power amplifier has the performance: In the frequency range of 6-18 GHz, small-signal gain of 13.5±1 dB, input/output VSWRs better than 2:1, 300 to 450 mW output power, and greater than 15 percent power-added efficiency (PAE). The MMIC amplifier was fabricated by 0.25μm power pHEMT standard process in the 4 inch GaAs MMIC FAB line. The MMIC chip size is 2.7 mm × 1.25 mm × 0.08 mm.
