Abstract: The concept of a compact and extremely low-power consuming Superconducting Integrated Receiver is being studied for 7 years. The initial idea has been realized in 1992 by integration of FFO with a SIS mixer into the sensitive mm-wave waveguide receiver with internal LO at about 150 GHz. To take most advantages of the integrated circuit technology, the series of quasioptical integrated lens-antenna receivers has been designed and tested in sub-mm wave range (400-700 GHz) including 9-pixel Imaging Array Receiver at 500 GHz. Looking forward to a new generation of more complex superconducting receiving devices which can hopefully be operated in conjunction with RSFQ processors, a number of RF components such as a variable microwave attenuator, RF SQUID-amplifier, SIS harmonic mixer and SIS multiplier are developed or are under extensive development. Recent success in phase-locking of FFO at 270-440 GHz opens very good prospects on practical implementation of Integrated Receivers for both radio astronomy and laboratory use.
