A novel low voltage inductor-less CMOS even-harmonic mixer for 5 GHz industrial scientific medical (ISM) band direct conversion receiver in an 0.18-mum SiGe Bi-CMOS process is presented. A voltage bias offset transconductance linearization is used with the even-harmonic mixer to achieve high IIP2 of 43.6 dBm, IIP3 of 0 dBm, and voltage conversion gain of 8.05 dB with 0.5% gm mismatch, 0.5% load mismatch...
A dual-band direct-conversion RF transceiver for IEEE 802.11 a/b/g WLAN is implemented in 0.18 /spl mu/m CMOS technology with 6 mm/sup 2/ die size and 182 mW power dissipation while transmitting 1 dBm at 5 GHz. The receiver achieves 5 dB NF, -8 dBm IIP3 (high LNA gain), 96 dB total gain, and -31.4 dB EVM. The transmitter achieves 1 dBm and 2.5 dBm linear output power at 5 GHz and 2.4 GHz, respectively,...
