Abstract :
We report for the first time the large-signal power performance of a MMIC amplifier based on GaInP/GaAs HBT´s. A output power of 9.9 W and power-added efficiency of more than 30% are measured at X-band. These results compare favorably with those measured from AlGaAs/GaAs HBT´s, demonstrating that GaInP/GaAs HBT´s are suitable for microwave power applications.<>
