摘要: 设计了一种覆盖SCX波段的高效率、小型化、重量轻、高性能射频功放模块。该功放模块基于氮化镓MMIC功率放大器,通过合理排布电路结构,优化电路布局,实现了模块的高效率和小型化,同时也保证了射频、电源和控制信号的完整性。该功放模块采用垂直传输结构来实现,并借助三维仿真软件对电路版图进行优化仿真,进一步提高了工艺的可操作性和模块的可靠性。通过对该功放模块进行热仿真分析,满足高温、低气压、大占空比、长时间工作的要求。最终设计出来的功放模块尺寸仅为46.2 mm×36 mm×12 mm。实测结果表明,小信号增益≥49 dB,饱和输出功率≥20.9 W,工作效率为31.6%。该功放模块带宽较宽、体积较小、性能可靠稳定,在无线通信、电子对抗等领域具有较高的应用价值。

Abstract: A RF power amplifier module covering SCX band with high efficiency, miniaturization, light weight and high performance is presented. The power amplifier module is based on GaN power amplifier, through reasonable arrangement of circuit structure, and optimizing circuit layout, the high efficiency and miniaturization of the module are realized. It also ensures the integrity of RF, power and control signals. The power amplifier module adopts vertical transmission structure. With the help of 3D simulation software, the circuit board diagram is optimized and simulated, and the process operability and module reliability are further improved. Through the thermal simulation analysis of the power amplifier module, it can meet the requirements of high temperature, low pressure, high duty cycle and long working time. The final design of the power amplifier module size is only 46.2 mm×36 mm×12 mm. Test results show that small signal gain≥49 dB, saturated output power≥20.9 W, and work efficiency is 31.6%. The power amplifier module has wide bandwidth, small size, reliable and stable performance, and has high application value in wireless communication and electronic countermeasures.
