VICKERS放大器EEA-PAM-533-A-32天津经销

VICKERS威格士比例放大器拓扑消除了直流偏置电流且极大地降低了功耗，其输出三极管以推拉方式分别受到控制，让MH器件为扬声器提供正向电流，而ML器件则吸收反向电流。这就降低了输出级的功耗，只有信号电流流过两个三*。

VICKERS比例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。
