Abstract :
This work summaries the RAL Schottky diode component performance from 166 to 664 GHz. These mixers and frequency multipliers employ either discrete GaAs Schottky diodes soldered on quartz substrates or integrated GaAs membrane Schottky diodes. Schottky diode-based sub-millimetre wave receivers are a key enabling technology for remote sensing of the Earth´s Atmosphere. Various mixers and frequency multipliers have been developed to cover different frequency bands from 166 to 664 GHz, and are dedicated to various on-going projects. For example, mixers at 166, 183 and 325 GHz are under-going preliminary reliability assessment for the European MetOp Second Generation satellites. More results will be presented in the seminar.
