管理功率放大器的方法和装置
摘要：
本发明公开一种管理功率放大器的方法和装置。在用于功率放大器的功率管理的本技术中，评估(826)功率放大器中多个放大器组中的已经关闭了最长时间段的放大器组，以提供最低放大器组。通过这个最低放大器组，评估(828)与最低放大器组相关联的上阈值，接着再评估(820)功率放大器的当前功率输出。接下来，确定(830)当前功率输出是否至少以预先确定的方式对应于上阈值，如果是的话，相应地接通(832)最低放大器组。
摘要（英）：

In the present technique for power management of a power amplifier, an amplifier bank from a plurality of amplifier banks in a power amplifier that has been switched off for a longest period of time is assessed ( 826 ) to provide a lowest amplifier bank. With this lowest amplifier bank, an up-threshold that is associated to the lowest amplifier bank is assessed ( 828 ), followed by another assessment ( 820 ) of a current power output of the power amplifier. It is next determined ( 830 ) whether the current power output corresponds at least in a predetermined way to the up-threshold, and if so,the lowest amplifier bank is accordingly switched on ( 832 ).
