NEW RFIC TRANSCEIVER ARCHITECTURE AND METHOD FOR ITS USE

摘要

A method of converting RF to base-band signals, or base-band to RF signals, using a novel receiver and transmitter architecture, implementable on a RFIC. The method uses a two-stage conversion sequence: RF to base-band followed by base-band to intermediate frequency in the receiver, and an opposite sequence in the transmitter. A preferred embodiment of the architecture uses a double balance quadrature demodulator (208)for the RF to base-band down-conversion, and an image reject quadrature modulator (230)for the base-band to intermediate frequency conversion. The architecture is further enhanced to perform power saving and dual-band reception and transmission.
