A METHOD OF RECEIVING AND TRANSMITTING THE SIGNAL OF HIGH FREQUENCY

摘要

The invention discloses a method of receiving and transmitting the signal of high frequency, belongs to the field of communication. During the frequency conversion filtering-frequency conversion of signal that is waiting for receiving and transmitting, the frequency of the local oscillator in the circuit and the central frequency of the filter make relevant change according to the time. When receiving, the disturbing signal, especially, the mirror image disturbing signal can be effectively restrained ; when transmitting, the influence of scrambled component and the leaking of the local oscillator to the receiving circuit and the channel can be reduced. The method of the invention can make the volume of the transmitting/receiving circuit more minished, easily integrated, agilely set and less costly.
