摘要
对设计的低压宽带功放的指标进行了介绍,并对设计功放所涉及的理论进行研究和讨论,在对所选用的功放管在厂家没有提供S参数的情况下进行了相关单管测试和验证,给出了参数优化后结果,根据分析以及计算后对功率放大器进行设计,对功率放大器做了硬件设计调试,并给出板级相关指标的测试结果。结果表明,该设计符合要求。
The power amplifier of one military shortwave radio is designed. The index of designed broadband tow-voltage power amplifier is introduced, the theories involved in the power amplifier design are discussed and researched, and the related single tube test of the selected tube is performed on the condition that S parameters of the relevant circumstances did not pro vided by manufacturers. The optimized parameter results are given, the hardware debug of the power amplifier is carried on, and the test results are proposed.
