66 -- 340 GHZ DUAL-POLARIZED RECEIVER SOL NRMGL000800880JW DUE 062998 POC Jacqueline Wright (303) 497-5282, FAX (303) 497-3163 E-MAIL: NOAA; MASC Acquisitions Management, Brenda.S.Summers@noaa.gov. The National Oceanic and Atmospheric Administration Environmental Technology Laboratory (ETL) has a requirement for the fabrication and delivery of a 340 GHz dual orthogonally-polarized single-conversion double- sideband superheterodyne receiver for radiometer applications with the following specifications: (1) IF bandwidth from 0.5-2.5 GHz, (2) planar beam- lead Schottky mixer diodes, (3) operating temperature range -40 to 40 degrees C, (4) RF center frequency drift less than +/-50 MHz over temperature range, (5) focussed feedhorn and rexolite lens with 1.5 inch aperture, less than 1.8 degrees 3dB beamwidth, greater than 93% main beam efficiency, f/D~3, (6) DSB noise figure less than 13 dB, matched IF amplifiers through detectors with nominal -23 dBm signal power. One of three possible configurations are preferred: (a) two identical but separate receivers with individual feedhorns driven by phase coherent local oscillator signals and using a wire grid to split the orthogonal polarizations behind a single lens, (b) a symmetric, integrated, dual orthogonally-polarized receiver using a single feedhorn and lens, or (c) two identical separate receivers with separate feedhorns and lenses. For a or b, either a pair of phase-locked LO's or single dual-output LO should be used. For c, two unlocked LO's can be used. Interested sources must submit a written qualification statement along with the request for the bid package by June 29, 1998. Responses must reference Synopsis No. NRMGL000800880JW. This announcement/solicitation is being issued under the Simplified Acquisition Procedures, FAR Part 13 (NTE $100,000.00). The award decision will be based upon the best value to the Government, with technical merit and past performance being significantly more important than price.
