The thermal and electrical performance of the InGaP/GsAs HBT device was analyzed. Considering the characteristic of good high power HBT amplifier chip, such as the performance, stability, reliability and size, an optimized HBT power cell and matching circuit were designed. A high-power, high efficient and small size ISM band MMIC power amplifier was developed. The three-stage MMIC amplifier fabricated with 320μm~2, 1 280μm~2, 5 760/μm~2 emitter area and the die size including the input and output 50Ω matching circuit is 1.9mm × 2.1 mm. When powered by a single 5 V power supply, it exhibits an output power of 37 dBm at 2 dB of gain compression point, a linear gain of 27 dB and an associated PAE of 46% in the frequency range of 2.4 to 2.5 GHz.
