Abstract

This paper presents a fully integrated Ku-band low noise block (LNB) front-end receiver with high image suppression capability. It translates the RF-band (10.7-12.75 GHz) to an IF ranging in the L-band (0.95-2.15 GHz). The receiver exhibits a conversion gain of 50 dB, a single-sideband noise figure of 3.8 dB and image suppression level of 40 dB. The integrated receiver draws 80mA from 1.1 V supply voltage. This paper demonstrates the feasibility of a Ku-band heterodyne receiver implemented on a 65nm CMOS technology.
