59 -- BAND PASS FILTERS SOL RFQBF6435 DUE 040500 POC Rena Cerbone, Contracting Officer, Tel: 617-495-7445, fax: 617-495-7485, email: rcerbone@cfa.harvard.edu The Smithsonian Astrophysical Observatory (SAO) intends to award on a sole source basis, a purchase order to RLC Electronics, Inc. of Mt. Kisco, New York for a follow-on procurement of two-hundred and twenty-five (225) ea P/N: F-10752, custom designed Band Pass Filters. These filters are designed to stringent SMA specifications and are packaged to fit into the existing correlator second down converter assemblies. These filters have a center frequency of 153MHz, the passband range is 112 to 194MHz, the flatness across the passband is +/- 0.75 dB (max), Input VSWR 1.5:1 (max), the maximum insertion loss can be no greater than 3 dB, input power handling +20 dBm (min), group delay deviation from center frequency: +20nsec (max), residual phase variation from nominal: +/- 18 degrees (max), group delay stability (passband) 20 psec/C (max) and must meet all specifications in the temperature range of 10-70 degrees C. while at an altitude of 14,000 feet. A determination by SAO not to compete this proposed purchase order based upon responses to this notice is solely within the discretion of SAO. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. This acquisition is being conducted under the guidelines as set forth in the Simplified Acquisition Procedures (SAP). No written solicitation will be issued for this requirement.
