SPEC.142082.26.0379.2200733-A.pdf

This is a Vendor Item Control Drawing for a diode detector component used by the National Weather Service WSR-88D Radar Operations Center located in Norman, Oklahoma.

The drawing specifies a zero bias detector diode with negative polarity, SMA connectors (male input, female output), maximum input power greater than 20 dBm (100mW), length less than 2 inches (50.8mm), voltage sensitivity of 0.5 mV/μW ±10%, VSWR of 1.5:1 or better, and a minimum frequency span of 2.6GHz to 3.1 GHz. Environmental specifications include indoor operating temperatures from +10°C to +35°C, non-operating temperatures from -35°C to +60°C, operating humidity of 20 to 80 percent, non-operating humidity of 15 to 95 percent, and altitude capability up to 3300 meters above mean sea level. Three suggested sources of supply are identified: Pasternack Enterprises, Inc. (CAGE Code 53919) in Irvine, California; NARDA-MITEQ (CAGE Code 99899) in Hauppauge, New York; and Eclipse MDI (CAGE Code 1XDA1) in San Jose, California. The specific part number for the diode detector is identified by dash number -201, with corresponding part numbers from each manufacturer: PE8012 (Pasternack), 4506 (NARDA-MITEQ), and EZM0140A3 (Eclipse MDI). Any substitution of parts from alternative sources requires review and concurrence by the WSR-88D Radar Operations Center and acceptance inspection by the National Reconditioning Center.
