Abstract

A highly integrated RF transceiver for GSM/GPRS/EDGE application is implemented in a 65nm SOC with BT and FM systems. Techniques are employed to minimize the coupling and interference effects among three wireless systems and results show the sensitivity and the output spectrum stay unchanged. The EDGE digital low-IF receiver achieves -110dBm sensitivity and -9dBm IIP3; while the EDGE polar transmitter achieves an ORFS of -66dB at 400kHz. This transceiver consumes 61/60mA in RX/TX EDGE modes.
