Abstract

Experimental results obtained by studying the main characteristics of a millimeter–submillimeterwave mixer based on the hot-electron effect in a two-dimensional electron gas in a AlGaAs/GaAs heterostructure with a phonon-scattering cooling mechanism for charge carriers are reported. The gain bandwidth of the mixer is 4 GHz, the internal conversion losses are 13 dB, and the optimum local-oscillator power is 0.5 µW (for a mixer area of 1 µm2 ). It is shown that a millimeter–submillimeter-wave receiver with a noise temperature of 1900 K can be developed on the basis of a AlGaAs/GaAs mixer. This mixer also appears to be promising for use in array receiver elements. Translated from Fizika i Tekhnika Poluprovodnikov, Vol. 39, No. 9, 2005, pp. 1117–1121.
