Abstract

We are presenting design details for an integrated heterodyne terahertz receiver based on phonon-cooled NbN HEB mixers directly coupled to wide-band InP MMIC IF amplifiers as an extension to our previous work. Measured noise and stability performance are reported for 1.6 THz and 2.5 THz. Finally, we discuss how this configuration can be extended to be used in large focal plane arrays, using multilevel array architecture.
