THz Low Noise Mixers for Sub-mm Astronomy
Paper in proceeding, 2016
In this work we demonstrate that the MgB2 HEB mixer with a Tc of 22K can operate above 12K with just a 25% increase of
the receiver noise temperature compared to that at 4.2 K. The GBW of 3.5 GHz was archived with a relatively thick film (a typical film thickness for NbN HEB mixers is 3–5 nm).
