    Microwave Loss Reduction in Cryogenically Cooled Conductors

    Measurements of microwave attenuation at room temperature and 4.2 K have been performed on some conductors commonly used in receiver input circuits. The reduction in loss on cooling is substantial, particularl...

    A Low Noise 100 GHz Sideband-Separating Receiver

    We have built a 100 GHz sideband-separating receiver. The receiver, a breadboard for the band 3 cartridges for ALMA, achieves a SSB noise temperature of 6hf/k with a 4–8 GHz IF. We show that it is possible to ...

    Some recent developments in the design of SIS mixers

    SIS mixers in which superconducting tuning elements are integrated with the tunnel junctions have resulted in very low noise heterodyne receivers in the range 68–260 GHz. Above ∼120 GHz the need for extremely ...

    Integrated tuning elements for SIS mixers

    The use of inductive elements to tune out the junction capacitance in SIS mixers is examined. Two new integrated tuning structures are introduced which overcome the limitations of earlier designs.
