Abstract: In accordance with an embodiment of the disclosure, systems and methods are provided for multi-modal power amplification. In certain implementations, an adjustable power amplifier amplifies an input signal, and the amount of amplification is varied based on the input signal. A variable impedance unit receives an amplified input signal, and the amount of load impedance at the variable impedance unit is varied based on the input signal.

Abstract translation: 根据本公开的实施例，提供了用于多模式功率放大的系统和方法。 在某些实施方案中，可调功率放大器放大输入信号，并且放大量基于输入信号而变化。 可变阻抗单元接收放大的输入信号，并且可变阻抗单元处的负载阻抗量基于输入信号而变化。
