摘要：

A new heterodyne receiver has been developed for the submillimeter wavelength region. The mixing element is liquid helium cooled bulk n-InSb in a quantizing magnetic field. The value of the magnetic induction is such that the detector photoresponse is dominated by cyclotron-resonance absorption. Laboratory tests have yielded double-sideband receiver noise temperatures of 250 K at 492 GHz, 350 K at 625 GHz and 510 K at 812 GHz. The magnetic induction for these tests was approx. 2. 5 KG and the mixer operating temperature was approx. 1. 6 K.
