Radio frequency generator for a radio communication system

摘要

A radio frequency generator in a radio communication system having a transmitter for up-converting the frequency of transmission data signals, and a receiver for down-converting the frequency of reception data signals includes: a first radio frequency generator for generating a low-band reception local oscillator frequency signal which is provided to a second mixer in the receiver; a second radio frequency generator for generating a low-band transmission local oscillator frequency signal which is provided to a first mixer in the transmitter; and a third radio frequency generator for generating a high-band local oscillator frequency signal for a first mixer of the receiver and a second mixer of the transmitter. A reference frequency generator is provided for receiving a radio frequency signal from a global position system receiver and generating a reference signal for generating local oscillator frequency signals in response thereto.
