| 摘 要： | 基于InGaP/GaAs HBT工艺设计了一款工作频段为2.5～2.7 GHz的高效率低谐波失真的功率放大器.该功放通过在输出匹配网络中引入多个LC谐振网络组合有效抑制了在负载处的高次谐波能量,进而提高了效率.仿真结果表明,该功率放大器在4.5 V的供电电压下,可以在2.5～2.7 GHz工作频率范围内实现37.6 dB的高增益输出,饱和输出功率可达32 dBm以及对应大于36%的功率附加效率(PAE),二次和三次谐波都小于-60 dBc.

| Abstract: | A 2.5-2.7 GHz Power Amplifier (PA) with high efficiency and low harmonic distortion in InGaP/GaAs HBT technology is designed.Multiple LC tanks are introduced into the output matching network of the presented PA to suppress the high-order harmonic distortions and improve efficiency.The simulation results show that, the PA achieves a high gain of 37.6 dB and a saturated output power of 32 dBm with Power Added Efficiency (PAE) of 36% at the saturated situation.The second and the third harmonic are both less than -60 dBc. |
