High-resolution computer-controlled oscillator of 2-mm wave-range for the low temperature dielectrometer

Abstract

High-resolution computer-controlled oscillator of 2-mm wave-range intended for the low temperature dielectrometer was designed and constructed. The proposed oscillator unit may be used as free-running source as well as phase locked source being included to the frequency synthesis system. Dependence of dielectric loss vs temperature for some diamond-like materials was measured using proposed oscillator unit within frequency range 110 and 145 GHz and at temperatures within 1 and 300 K.
