Abstract

Here we report on the design of the 4×2 HEB quasi-optical mixer array at 4.7 THz for GUSTO. Two studies are presented. The first is a statistical analysis of some of the key parameters of HEB devices within a single batch. In a population of 10 randomly selected devices we show a state of the art noise temperature of 720 K at 2.5 THz with only 3 % spread, while at the same time meeting LO uniformity requirement. The second study discusses the impact of different diameter elliptical lens on receiver performance. We conclude that 10 mm lens offers the best performance with the lowest risk to the project. At the same time we confirmed the value of 11.4 for the ξSi of silicon at 4.2 K. Furthermore, we describe the mixer array mechanical design resulting in a compact monolithic unit.
