  • Patent number: 8213927
    Abstract: 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.
