Abstract
Monolithic power amplifiers using adequately ballasted high-efficiency GaInP/GaAs heterojunction bipolar transistors (HBT's) have been desig ned, fabricated, and tested. A maximum output power of 9 W with a powe r-added efficiency (PAE) of 42% and peak power-added efficiencies of 4 5% have been achieved at 10 GHz under critical long pulse conditions ( pulse width = 100 mu s, duty cycle = 10%). To our knowledge these resu lts represent the best performance of any GaInP/GaAs HBT MMIC power am plifier considering efficiency, output power, operation frequency, and pulse conditions.
