About single block with receiver and frequency-meter in Terahertz band at the base of Josephson junction

On the basis of previous theoretical and experimental investigation, here we propose the design of a super wide panoramic receiver-frequency-meter (PRF) based on the Josephson junctions (JJ). This solution is particularly suitable for experimental purposes rearding new generation structures for which radiative power is small and operating frequency is not accurately known. In particular, we present two devices based on the JJ. The first one is the receiver based in self-pump mode regime of JJ and second one is a super wide frequency-meter.
