Abstract :
The CMOS transceiver IC uses the superheterodyne architecture to implement a IEEE 802.11g RF front-end with auto I/Q calibration function. 1° quadrature mismatch and 0.1 dB gain mismatch can be achieved after the auto tuning in both the transmitter and receiver sides. Implemented in a 0.25 μm CMOS process with 2.7 V supply, the transceiver achieves a 5.1 dB receive cascade NF and a 7 dBm transmit output P1dB.
