The transceiver supports I/Q gain and phase mismatch auto tuning mechanisms at both the transmitting and receiving ends, which are able to reduce the phase mismatch to within 1° and gain mismatch to 0.1 dB. Implemented in a 0.25 μm CMOS process with 2.7 V supply voltage, the transceiver delivers a 5.1 dB receiver cascade noise figure, 7 dBm transmit, and a 1 dB compression point. © 2005 IEEE. |
