Wireless transceiver for supporting a plurality of communication or broadcasting services

摘要

A wireless transceiver for receiving and processing a wireless local area network (WLAN) radio frequency (RF) signal and a satellite Digital Multimedia Broadcasting (DMB) RF signal, and generating and transmitting a WLAN RF signal, is provided. The wireless transceiver includes a reception antenna for receiving the WLAN RF signal or the satellite DMB RF signal; a quadrature demodulator for down-converting the received signal into a baseband signal, based on a local oscillator signal, and providing the baseband signal to a baseband processor; and a local oscillator signal generation unit which is configured to generate the local oscillator signal according to whether the received signal is a WLAN RF signal or a satellite DMB RF signal.
