Abstract

A method for the generation of stable, widely tunable heterodyne oscillations by means of a high-temperature-superconducting resistive superconducting quantum interference device is described. The details of the fabrication techniques, electrical characteristics, operating temperatures and frequency range of 100 MHz-2 GHz, are reported. The noise temperatures of several devices, made and tested in different laboratories, are estimated and the linewidths of the heterodyne oscillations are compared with theoretical values.
