Abstract:
We report a remarkable progress in the development of highly packaged heterodyne receivers using NbN HEB mixers and MMIC IF amplifiers. We are presenting a record IF noise bandwidth of 8 GHz (measured for a ~700 GHz LO) using a lumped element matching network for the input of the IF preamplifier. Further, we describe the first three-dimensional (3-D) integration of a sub-millimeter mixer and its pre-amplifier using a simple vertical feed-through structure. Thereby, we achieve a volume shrinkage of at least 20 times, accompanied by a mass reduction of 15:1. These receivers bring promise for the implementation of large-format arrays for heterodyne terahertz sensing applications.
