摘要: We report on the development of STEAMR radiometer system, including front-end receivers, LO multipliers and back-end spectrometer system. constitutes submillimeter wave limbsounder board PREMIER, one three ESA Earth Explorer Core missions that have entered a feasibility study phase. The instrument is based linear array 14 heterodyne receivers operating in 320 GHz to 360 band processing over 260 instantaneous IF bandwidth. Thereto, eight fourteen are be sideband separating (2SB) novel waveguide topology with integrated LNA’s has been developed. An overview receiver system presented together conceptual design optimized meet scientific goals instrument. Preliminary results critical components such as mixers, chains back end different alternatives for realization discussed.
