| description | The invention belongs to the field of solid-state microwave power amplifiers, relates to an excitation signal triggered power amplifier overshoot suppression efficiency improvement method, a circuit and a power amplifier. The problem that a power amplifier is low in stability or efficiency is solved. The part, in front of a microwave excitation signal, of the pulse power amplifier works in a high-efficiency class B; before the falling edge of the excitation signal arrives, the grid voltage control circuit is used for adjusting the grid bias voltage, the working type of the power amplifier is changed, and the grid bias voltage is adjusted to the type A, so that the power amplifier works in the type A at the moment of the falling edge of the excitation signal, and the drain voltage does notgenerate overshoot at the moment of closing the microwave excitation signal.
本发明属于固态微波功率放大器领域，涉及一种激励信号触发下功放过冲抑制效率提升方法、电路及功放，旨在解决功率放大器稳定度低或者效率低的问题，本发明脉冲功率放大器在微波激励信号前面部分工作在高效率的B类，在激励信号的下降沿到达前通过栅压控制电路调整栅极偏置电压，改变功率放大器工作类别，将栅极偏置电压 |
