A 160-GHz low-noise downconversion receiver front-end in a SiGe HBT technology
Published online by Cambridge University Press: 15 March 2011
Abstract
A 160-GHz SiGe-HBT (Heterojunction Bipolar Transistor) down-conversion receiver front-end for use in active millimeter-wave imaging arrays and D-band communication applications is presented. The monolithic front-end consists of a three-stage low-noise amplifier providing 24 dB of gain and a Gilbert-cell mixer capable of operating from a −8-dBm LO signal. A fully differential architecture compatible with balanced on or off-chip antennas is used to avoid the need for on-chip baluns in antenna-integrated applications. The implemented downconversion front-end consumes 50 mA from a 3.3 V supply and requires a 0.1 mm2 die area (excl. pads) per channel. With a 160-GHz input signal and an Intermediate Frequency (IF) of 1 GHz, the implemented front-end yields a 25-dB conversion gain, a −30-dBm input compression point, and a 9-dB/7-dB (with/without auxiliary on-chip input balun) system noise figure.
