Statement of Work Radio Frequency Control Hardware 09/24/2015

1.0 Scope/Background

The Radio Frequency (RF) Systems and Development branch (Code 472200D) of the Naval Air Warfare Center Weapons Division, China Lake (NAWCWD is upgrading the Hardware in the Loop (HiL) facility located in Chamber 1 of Building 2720. The Government intends to procure one hundred eighteen (118) 11 Bit Digital PiN Diode Attenuators, fifty (50) Single Pole Three Throw (SP3T) Switches, one hundred (100) Single Pole Eight Throw (SP8T) Switches, and four (4) Phase Shifters. The components shall be used for modulating signal paths and also for controlling synthetic targets on the array wall.
