Abstract
A high power gain, low noise WLAN receiver, using a 158 GHz fT 90-nm RF CMOS technology for dual IF double downconversion system-in-package application is demonstrated. The proposed circuit could improve the design flexibility of back-end stages due to its high power gain and low noise performances. The LNA and Mixer are biased at 1 V with 12.9 mA and 1.8 V with 5.5 mA, respectively. The proposed circuit delivers the double-sideband noise figure of 2.68 dB, conversion gain of 36.24 dB, IIP3 of -25 dBm, IIP2 of 21.1 dBm, and LO-IF isolation of -56.2 dB under the 1 dBm LO power, while maintaining the RF port and IF port return losses below -12.9 and -18.7 dB, respectively.
