RF MODULE AND WIRELESS COMMUNICATION DEVICE

摘要

A radio frequency module of a wireless communication device is provided. The radio frequency module is coupled between an antenna and a micro-control unit and includes a radio frequency front-end, a radio frequency integrated circuit, a baseband low-pass filter and a comparator. The radio frequency front-end receives a radio frequency signal through the antenna. The radio frequency integrated circuit receives the radio frequency signal from the radio frequency front-end and converts the radio frequency signal into a baseband signal. The baseband low-pass filter receives the baseband signal from the radio frequency integrated circuit and filters the baseband signal. The comparator compares the filtered baseband signal with a first reference signal and outputs a comparison result signal to the micro-control unit.
