摘　　要：通过分析InGaP/GsAsHBT器件的热学和电学特点,结合HBT大功率放大器芯片在技术性能、稳定性、可靠性及尺寸等方面的要求,通过优化设计HBT功率器件单元和匹配电路,开发了一个大功率、高效率、小尺寸的ISM波段功率放大器单片集成电路。该三级放大器的各级器件单元的发射极面积分别为320μm2,1280μm2,5760μm2,芯片内部包括了输入、输出50Ω匹配电路,面积仅为1.9mm×2.1mm。放大器采用5V单电源供电,在2.4～2.5GHz频率范围内线性增益为27dB,2dB增益压缩点输出饱和功率达到37dBm,功率附加效率为46%。Abstract： 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 320 μm2, 1 280 μm^2, 5 760 μm^2 emitter area and the die size including the input and output 50 12 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.
