Abstract :
A zero-IF, 4.9-5.95 GHz, 2.3-2.5 GHz, transceiver is fabricated on a 0.18 μm CMOS process. By using a fractional-N synthesizer, an integrated phase error of 0.6° (0.7°) at 5 GHz (2.4 GHz) is achieved, while supporting fine frequency resolution. Digital calibration eliminates I/Q mismatch and achieves accurately matched baseband filters. The transceiver is compliant to 802.11a/b/g, while programmable bandwidth filters and an EVM of -35 dB in both transmit and receive, make it suitable for applications based on 802.16d/e.
