Power amplifier Modules were designed using Push-Pull BJT power amplifiers that were combined using 3db Quadrature couplers.
功率放大器模组设计，使用负载牵引特性原理功率放大器被合并使用三分贝正交耦合器。
For audio amplification, a class a amplifier can be either single-ended or push-pull.
对于音频放大，一个A类放大器可单端或推挽。
When designing output stage, in order to enhance the efficiency, it uses the push-pull common source stage amplifier as the output stage, the output voltage swing basically reached rail-to-rail.
在输出级设计时，为了提高效率，采用了推挽共源级放大器作为输出级，输出电压摆幅基本上达到了轨至轨；
