Embodiment Construction

[0025] In general, according to these various embodiments, the amplifier bank of the plurality of amplifier banks of power amplifiers that has been turned off for the longest period of time is evaluated to provide the lowest amplifier bank. From this lowest amplifier group, the upper threshold associated with the lowest amplifier group is evaluated, followed by the current power output of the power amplifier. Next, it is determined whether the current power output corresponds at least in a predetermined manner to the upper threshold, and if so, the lowest amplifier bank is switched on accordingly.

[0026] In one embodiment, before evaluating the lowest amplifier bank, the current power output of the power amplifier is evaluated, the previous power output is set as the current power output, and the method is repeated waiting for a predetermined period of time. According to one embodiment, the previous and current power outputs of the power amplifiers are evaluated to determine...

Abstract

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 ).

Description

[0001] Related Application Citations [0002] This application is related to co-pending application entitled "METHODS AND APPARATUS OFMANAGING A POWER AMPLIFIER," filed on the same date, which is assigned to the assignee of this application and is hereby incorporated by reference. technical field [0003] The present invention generally relates to methods and apparatus for managing power amplifiers. Background technique [0004] It is well known that cellular base station power amplifiers are most efficient when operating at their rated power. These power amplifiers are usually capable of handling the maximum power required by the cell site when it is busiest. To save power, it is common to include elements in the device-level structure of a power amplifier to put unneeded overhead resources to sleep. These elements are often complementary to other effective improvements. Because most of these prior art components are not backward compatible with legacy devices, they can ...
