Abstract
Submillimeter-wave space applications require special components for power generation, detection and multiplication. This article presents recent progress in three various solid-state device technologies for submillimeter-wave space instruments: the InP HEMT for ultra-low noise detection at very low power in the IF amplifier, the heterostructure barrier varactor in the frequency multiplier, and the superconducting hot electron bolometer mixer for quantum-limited heterodyne detection above 700 GHz.
