具有失配容忍度的RF功率放大器电路制造技术

一种射频(RF)功率放大器系统响应于功率放大器(PA)的RF输出信号的测量或估计功率，自适应地调整向该PA提供的供应电压。该RF?PA系统包括功率放大器(PA)，其接收并且放大RF输入信号以在适合于天线传输的水平生成RF输出信号。PA供应电压控制器生成供应电压控制信号，该供应电压控制信号用于控制到该PA的最后一级的供应电压。响应于该RF?PA输出信号的测量或估计功率，并且还可以响应于用于指示在该PA输出处经历的阻抗失配的参数，生成该供应电压控制信号。通过控制该RF?PA的供应电压，提高该PA的效率。

RF power amplifier circuit with mismatch tolerance

A radio frequency (RF) power amplifier system adaptively adjusts the supply voltage supplied to the PA in response to the measured or estimated power of the RF output signal of the power amplifier (PA). The RF PA system includes a power amplifier (PA) that receives and amplifies the RF input signal to generate a RF output signal at a level suitable for antenna transmission. The PA supply voltage controller generates a supply voltage control signal for controlling the supply voltage to the last stage of the PA. The supply voltage control signal is generated in response to the measured or estimated power of the RF PA output signal and also in response to a parameter indicative of an impedance mismatch experienced at the PA output. By controlling the supply voltage of the RF PA, improve the efficiency of the PA.
