Development of 3–5 thz harmonic mixer
WebApr 1, 2008 · The characterization of a 1.1-1.7 THz planar Schottky-diode mixer is described. Initial measurements yielded a mixer noise temperature of 5900 K (DSB) and … Webdemonstrations of HTS THz mixers were mostly achieved in the temperature ranges below 20 K [3-6] and later at 58 K [7]. Recently, HTS THz mixers that operate up to 77 K have been demonstrated at CSIRO laboratory [8-11] using a step-edge junction technology [12]. Best noise and conversion performance at 600 GHz band were achieved [13].
