Abstract
Disclosed is a wireless communication system applicable to a time-division duplex transceiver system. The time-division duplex mobile communication system can achieve miniaturization, low power consumption and low costs by using a frequency conversion circuit including a mixer and an intermediate frequency (IF) circuit for both transmitter and receiver, and also can cope with multi-band, multi-application systems by using a broadband amplifier, a variable IF filter and a variable gain amplifier.
