原理:高频功率放大器用于发射机的末级,作用是将高频已调波信号进行功率放大,以满足发送功率的要求,然后经过天线将其辐射到空间,保证在·定区域内的接收机可以接收到满意的信号电平,并且不干扰相邻信道的通信。
高频功率放大器是通信系统中发送装置的重要组件。按其工作频带的宽窄划分为窄带高频功率放大器和宽带高频功率放大器两种,窄带高频功率放大器通常以具有选频滤波作用的选频电路作为输出回路,故又称为调谐功率放大器或谐振功率放大器;宽带高频功率放大器的输出电路则是传输线变压器或其他宽带匹配电路,因此又称为非调谐功率放大器。高频功率放大器是一种能量转换器件,它将电源供给的直流能量转换成为高频交流输出在 “低频电子线路”课程中已知,放大器可以按照电流导通角的不同,将其分为甲、乙、丙三类工作状态。甲类放大器电流的流通角为360o,适用于小信号低功率放大。乙类放大器电流的流通角约等于 180o;丙类放大器电流的流通角则小于180o。乙类和丙类都适用于大功率工作丙类工作状态的输出功率和效率是三种工作状态中·高者。高频功率放大器大多工作于丙类。但丙类放大器的电流波形失真太大,因而不能用于低频功率放大,只能用于采用调谐回路作为负载的谐振功率放大。由于调谐回路具有滤波能力,回路电流与电压仍然极近于正弦波形,失真很小。
