本文主要介绍的是高频谐振功率放大器的基本工作原理、工作状态以及外部特性。高频谐振功率放大器一般用于各种无线电发送设备中,对高频载波或高频已调波进行功率放大。在通信电路中,由于信号在传输过程中有一定的衰耗,而且通信距离越远,要求输出功率越大。所以为了获得足够大的高频输出功率,必须采用高频功率放大器。
This article describes the basic working principle of high-frequency resonant power amplifier, working conditions and external characteristics. High-frequency resonant power amplifier is generally used in a variety of radio transmission equipment, high-frequency carrier wave or high-frequency power amplifier has been modulated. In the communication circuit, due to the signal in the transmission process has a certain attenuation, and the longer the communication distance, the greater the required output power. Therefore, in order to obtain a sufficiently large high-frequency output power, a high-frequency power amplifier must be used.
