A 5-GHz Direct-Conversion CMOS Transceiver
نویسندگان
چکیده
A CMOS transceiver fully compliant with IEEE 802.11a in the unlicensed national information infrastructure (UNII) band (5.15–5.35 GHz) achieves a receiver sensitivity of 5 dBm for 64-QAM (quadrature amplitude modulation) with an error vector magnitude (EVM) of 29.3 dB. A single-sideband mixing technique for local-oscillator signal generation avoids frequency pulling. Realized in 0.18m CMOS and operating from 1.8-V power supply, the design consumes 171 mW in receive mode and 135 mW in transmit mode while occupying less than 13 mm.
