提高发送器的功率效率的系统和方法
摘要：
一种提高发送器的功率效率的系统和方法。根据本公开的一些实施例，一种电路包括平衡-不平衡变换器，该平衡-不平衡变换器被配置为在输入线圈的第一输入端口和第二输入端口处接收射频RF信号。该平衡-不平衡变换器还被配置为在通信地耦合到输入线圈的输出线圈处输出RF信号。该电路还包括供应电压选择器电路，该供应电压选择器电路耦合到输入线圈并且被配置为根据在输入线圈处接收的RF信号的功率水平来调整输入线圈处的偏置电压。
摘要（英）：

In accordance with some embodiments of the present disclosure, a circuit comprises a balun (234) configured to receive a radio frequency (RF) signal at a first input port and a second input port of an input coil (236). The balun (234) is further configured to output the RF signal at an output coil (238) communicatively coupled to the input coil. The circuit also comprises a supply voltage selector circuit (240) coupled to the input coil and configured to adjust a bias voltage at the input coil (236) according to a power level of the RF signal received at the input coil.
