177-207 GHz Radiometer Front End, Single-Side-Band Measurements

Abstract:
Twenty years of progress in 200 GHz receivers for spaceborne remote sensing has yielded a 180-220 GHz technology with maturing characteristics. The maturing characteristics are evident by increasing hardware availability —supply side—that parallels further refinement in receiver front-end (RFE) performance requirements—demand side—at this important spectrum band. The 177-207 GHz super-heterodyne receiver, for the Earth observing system (E0S) microwave limb sounder (MLS), effectively illustrates such technology developments. This MLS receiver simultaneously detects six different signals, located at side-bands below and above its 191.95 GHz local-oscillator (LO) frequency.
