Abstract

A 5.7 GHz 0.18μm CMOS gain-controlled differential LNA and a single-ended CMOS mixer for 802.11a WLAN applications are presented. The differential LNA, fabricated with the 0.18 μn 1P6M standard CMOS process, uses a current-reuse technology to increase linear gain and save power consumption. The single-ended CMOS mixer uses a single balance topology. Measurements of the CMOS components are performed by using a FR-4 PCB test fixture. The LNA exhibit noise figure of 3.7dB, linear gain of 12.5dB, P _1dB of -11dBm, and gain tuning range of 6.9dB. The mixer with a 280 MHz IF has a conversion gain -4.5dB, input P_1dB 0dBm, and noise figure 14.6dB. LO-RF isolation is 20dB and LO-IF Isolation is 24dB. The power consumption of the differential LNA is 14.4mW and that of the mixer is 10.4mW from a 1.8V power supply.
