We have used the Submillimeter Wave Astronomy Satellite to carry out observations on Jupiter and Saturn in two bands centered at 489 and 553 GHz. We detect spectrally resolved 557 GHz H2O emission on both planets, constraining for the first time the

The vertical profiles of ClO, HCl, HO2, and O3 were determined from thermal emission measurements by a balloon-borne spectrometer operating near 640 GHz. Results are in broad agreement with previous measurements and models, but differ significantly w

The performance of a broadband SIS (superconductor-insulator-superconductor) receiver with no mechanical tuning elements was modeled and tested. The mixer mount had a broadband-waveguide-to-microstripline transition consisting of a four-step Chebyshe

A balanced frequency doubler has been built using an integrated planar array of four varactor diodes. The maximum output power of 55 mW at 174 GHz is twice the power available from the previous best multiplier at a nearby frequency and was limited by

We have measured the full voltage dependence of the quantum conductance and quantum susceptance which arise, respectively, from the dissipative and nondissipative quasiparticle tunneling currents in a superconductor-insulator-superconductor tunnel ju

A broadband waveguide SIS (superconductor-insulator-superconductor) mixer with no adjustable mechanical tuning elements for the 75–110 GHz band was constructed and tested. The design is a demonstration of a prototype receiver element in a focal pla

We have made heterodyne radiometric measurements with GaAs Schottky diode mixers, mounted in a corner‐reflector configuration, over the spectral range 170 μm to 1 mm. At 400 μm, system noise temperatures of 9700 K DSB (NEP=1.4×10−19 W/Hz) and

A 3mm wavelength dual-beam radiometer utilizing quasi-optics and Schottky diode mixers has been developed at the Five College Radio Astronomy Observatory. This cryogenic system eliminates the need for mechanical beam or load switching, continuously s

A cryogenic receiver covering the 200-350 GHz range is described. Two Schottkydiode mixers cover this range, with the mixers and FET IF amplifier cooled to 20 K. LO power is provided by a frequency doubler/tripler, with a Martin-Puplett interferomete
