Low-noise broad IF band 240 GHz subharmonically pumped planar Schottky diode mixers for space-borne radiometers have been developed and characterized.
The authors report on the design, analysis and performance of an all GaAs MMIC multiplier for use at submillimeter wavelengths.
This paper reports on the first all solid-state two-diode subharmonically pumped (SHP) mixer operating at 640 GHz.
The design and performance of a 640 GHz solid-state receiver using a fundamental planar-Schottky-diode mixer, InP Gunn diode oscillator, whisker-contacted Schottky-varactor-diode sextupler and folded-Fabry-Perot diplexer are reported.
We report on a subharmonic mixer with a broad IF bandwidth that has been developed for the Microwave Instrument for the Rosetta Orbiter (MIRO) to study water transition lines occurring near 557 GHz.
Accelerated lifetime tests have been performed on intergrated planar GaAs Schottky diodes that were bonded to quartz substrates up-side-down with a heat-cured epoxy.
In preparation for the insturment ammouncement of opportunity for the Far Infrared and Submillimeter Space Telescope, and ESA/NASA space astrophysics observatory mission, local oscillator sources at high frequencies (1200 GHz) are being developed. As part of a multiplier chain beginning at ~100 GHz we are developing single and multiple diode waveguide circuits up to 640 GHz.
