    • A system and method of optimizing the output power of a power amplifier to maintain satisfactory RF response under varying power amplifier operating conditions. The operating conditions include operating temperature, supply voltage, and operating frequency. Existing sensors monitor the aforementioned operating conditions. An application within the wireless device containing the power amplifier continuously or periodically logs the current operating conditions and finds them in a look-up table stored internally. The look-up table is comprised of empirically derived maximum sustainable power output levels for each operating condition. Once the current operating conditions are matched to a set in the table, current power amplifier power output is reset, if necessary, to the maximum sustainable power output defined in the table.
    • 一种优化功率放大器的输出功率以在变化的功率放大器工作条件下保持令人满意的RF响应的系统和方法。 工作条件包括工作温度,电源电压和工作频率。 现有传感器监控上述操作条件。 包含功率放大器的无线设备内的应用连续地或周期性地记录当前的操作条件,并将它们发现在内部存储的查找表中。 查找表由每个操作条件的经验派生的最大可持续功率输出水平组成。 一旦当前工作条件与表中的一组匹配,当前的功率放大器功率输出将被复位,如有必要,可以达到表中定义的最大可持续功率输出。
