    • A mobile phone utilizes a radio frequency (RF) chip transceiving RF signals via a front end circuit. A power detector detects power output from a power amplifier and converts the power to voltage to transmit to a central processing unit (CPU). A base station tester measures output power of the mobile phone and transmits to the CPU in a test mode. A microwave chamber measures power radiated by the antenna in an operation mode. A high voltage circuit provides a high voltage signal continuously. A detection circuit detects a connection status of the base station tester and the testing connector and outputs the high voltage signal to the CPU according to the connection status. The CPU determines an operating mode of the mobile phone based on output of the detection circuit, and outputs a maximum output power according to the test mode and operation mode maximum output power calibration tables.
    • 移动电话利用射频(RF)芯片通过前端电路收发RF信号。 功率检测器检测功率放大器的功率输出,并将功率转换为电压以发送到中央处理单元(CPU)。 基站测试仪测量手机的输出功率,并以测试模式传输到CPU。 微波室在操作模式下测量由天线辐射的功率。 高压电路连续提供高电压信号。 检测电路检测基站测试器和测试连接器的连接状态,并根据连接状态向CPU输出高电压信号。 CPU基于检测电路的输出确定移动电话的操作模式,并根据测试模式和操作模式最大输出功率校准表输出最大输出功率。
