    • The present invention addresses the need for an apparatus and method for controlling the load of a PA, to improve PA efficiency in linear transmitters with isolator elimination (IE) circuitry, that does not require the use of high frequency RF circuitry. The present invention provides a PA load controller (130, 131) that improves the efficiency of a PA (116) by adjusting the PA load using an AGC signal (134), a level set adjustment signal (132), and a signal strength indicator (135), these three signals are readily obtained from continuous gain and phase adjustment circuitry (e.g., 102). The load controller determines a phase of the PA load that minimizes the AGC signal and a phase of the PA load that maximizes the level set adjustment signal. From these determinations, the PA load controller determines a phase of the PA load that improves the efficiency of the PA and adjusts the PA load phase accordingly.
    • 本发明解决了对用于控制PA的负载的装置和方法的需求,以提高不需要使用高频RF电路的隔离器消除(IE)电路的线性发射机中的PA效率。 本发明提供一种通过使用AGC信号(134),电平设定调整信号(132)和信号强度指示器(132)来调节PA负载来提高PA(116)的效率的PA负载控制器(130,131) (135),这三个信号很容易从连续增益和相位调整电路(例如102)获得。 负载控制器确定最大化AGC信号的PA负载的相位和使电平设置调整信号最大化的PA负载的相位。 从这些确定中,PA负载控制器确定PA负载的相位,从而提高PA的效率并相应地调节PA负载相位。
