TDMA TRANSCEIVER INCLUDING CARTESIAN FEEDBACK LOOP CIRCUIT, CAPABLE OF CONSTRUCTING LINEARIZATION CIRCUIT OF POWER AMPLIFIER WITH MINIMUM ADDITIONAL CIRCUIT ONLY

摘要

PURPOSE: A TDMA(Time Division Multiple Access) transceiver is provided to implement a Cartesian feedback loop at a minimum area without additional expenses by using a conventional receiver of a TDMA terminal. CONSTITUTION: The transceiver comprises a transmitter(120), a receiver(110), and a feedback module. The transmitter(120) modulates and amplifies signals to be transmitted via an antenna. The receiver(110) receives signals via an antenna and demodulates the received signals. The feedback module feeds back the transmission signals to the receiver to linearize the transmission signals by coupling the output signals of the transmitter(120) to an input end of the receiver(110) and coupling the output signals of the receiver(110) to an input end of the transmitter(120).
