| Popis: | We present results of a systematic work towards components for an integrated high-T/sub c/ receiver. As a local oscillator, which is necessary for heterodyne detection, the array type of the multi junction superconducting loop (MSL) was investigated. We observed the phase locking of all junctions by means of dc-measurements. At the same time the radiation of the array was detected using a detector junction coupled to the array. Phase locking of all junctions was achieved up to nearly 1 THz. Furthermore, the results of heterodyne mixing experiments in the W-band using single high-T/sub c/ grain boundary junctions are presented. The possible integration of Josephson oscillator and mixer into a single circuit is discussed. |
