How to Design an RF Power Amplifier: Class E 链接:pan.baidu.com/s/1UWQZ35 提取码:jhf4 这里可以总结下Class D类和E类功放的异同点:D类和E类起作用的都是串联LC谐振网络,都是通过开关让LC谐振网络在电源和地之间切换(D类采用inverter实现,E类采用开关和并联电容实现)。LC网络中不会有直流功耗,焦点...
The highly efficient operation of power amplifier can be obtained by applying biharmonic or polyharmonic modes when an additional single-resonant or multi-resonant circuit tuned to the odd harmonics of the fundamental frequency is added into the load network. An infinite number of odd-harmonic ...
