A 2.3-GHz to 5.8-GHz CMOS receiver front-end for WiMAX/WLAN

This paper presents a wideband, direct-conversion radio receiver front-end that targets all WiMAX/WLAN bands from 2.3-GHz to 5.8-GHz. The receiver front-end is fabricated in 0.18-µm CMOS and achieves a gain of 25 dB, noise figure of 6 dB, and IIP3 of −6 dBm while dissipating 28 mW from a 1.8-V power supply. This performance is achieved while using only two integrated inductors.
