Scientific paper

A heterodyne receiver is described in which an InSb hot electron
bolometer is used as a mixer. The local oscillator power is obtained by
doubling the frequency of a backward wave oscillator. The receiver
operates between 460 and 500 GHz (0.65 - 0.6 mm). Noise temperatures
amount typically to 1000 K.
