About this file
This is a Specifications document for the National Weather Service (NWS) Radar Operations Center (ROC) outlining requirements for RF attenuators to be used in NEXRAD receiver cabinets.
The procurement consists of two Contract Line Items (CLINs). CLIN 0001 requires 200 units of 6dB Attenuators (API Inmet 18AH-06 or equivalent) with specifications including 0.86-inch length, SMA male and female connectors with stainless steel passivated material, gold-plated beryllium copper conductors, maximum VSWR of 1.15:1 from DC-4 GHz, 2W average input power, and 0.3 dB accuracy. CLIN 0002 requires 200 units of 15dB Attenuators (API Inmet 18AH-15 or equivalent) with similar specifications except for 0.99-inch length and 0.5 dB accuracy. Both CLINs share identical environmental specifications: operating temperature range of +10°C to +35°C, non-operating temperature range of -35°C to +60°C, operating humidity of 20-80%, non-operating humidity of 15-95%, and altitude capability up to 3,300 meters above mean sea level. Delivery is to be made to NWS Radar Operations Center, Attn: Tammy Buie, 1200 Westheimer Drive, Norman, OK 73069.
