Ka频段固态集成功率放大器的设计

Design of Ka-band solid-state power amplifier

摘要:

毫米波系统已广泛应用于军事通信，作为核心部件的毫米波发射机，其输出功率为衡量系统性能指标的重要因素。本文运用混合集成的方法设计了一种Ka频段固态功率放大器，并结合实际情况分析了与调试相关的电路稳定性问题。测试结果表明，该放大器在f0±1.5 GHz的工作频带内，增益大于35 dB，P-1为30 dBm，达到设计要求。

Abstract:

Millimeter-wave systems have been widely applied in military communications. As a key component, the output power of millimeter-wave transmitter has become an important parameter to evaluate these systems’ performance. This study designed a Ka-band solid-state power amplifier, and analyzed the problems of circuit stability about debugging. The measurement result indicated that the gain was more than 35 dB within f0±1.5 GHz, and P-1 was 33 dBm.
