Abstract

ions Stefan Koch, Member , IEEE, Marc Guthoerl, Ingmar Kallfass, Arnulf Leuther, and Shin Saito Abstract—For passive mm-wave imaging applications, broad- band mm-wave receivers functioning within atmospheric windows are highly desired. Within this paper, a heterodyne receiver chipset utilizing the 140 GHz atmospheric window is presented. The heterodyne chipset is based on two different millimeter-wave monolithic integrated circuits (MIMICs). One is the receiver MIMIC including a low-noise ampliﬁ
