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.

Abstract: An electronic device (10) includes a substrate (11), a metal film (12), a radio frequency module (14), and a signal transmission portion (13). The substrate includes two opposite surfaces. The metal film is disposed on one surface of the substrate and defines a clearance (16) therein. The radio frequency module is disposed on the clearance. The signal transmission portion is electronically connected to the radio frequency module and the metal film, for transmitting electromagnetic signals between the radio frequency module and the metal film.
