摘要

采用JAZZ 0.35 μ m SiGe BiCMOS工艺设计了一种3.33 GHz-3.53 GHz卫星通信功率放大器。本功率放大器工作在AB类单端结构。当电源电压为3.3 V时，其中心工作频率的功率增益为23 dB，在1 dB功率压缩点可向50¿负载传输29.98 dBm输出功率，功率附加效率为33.84%。仿真结果表明，该系统输入输出匹配良好，工作稳定。

3.43GHz power amplifier design for satellite communications

A 3.33 GHz-3.53 GHz power amplifier for satellite communications is designed by using JAZZ 0.35 ¿m SiGe BiCMOS process. This power amplifier works in class AB type with single-ended structure. With a supply voltage of 3.3 V, the power gain is 23 dB at its center operation frequency and it can transmit 29.98 dBm output power to a 50 ¿ load at 1 dB power compression point with 33.84% power added efficiency. The simulation results show that the input and output matching are well and it can work stably.
