Abstract : This final report describes the results achieved on the High Temperature Superconductors for Electronic Warfare Applications program. The objective of this program was to demonstrate beamforming network (BFN) components using High Temperature superconductors (HTS) operating between 50 and 70 K from 2-18 GHz intended for Electronic Warfare (EW) subsystems for early insertion. In particular, this program addressed three tasks; the first task developed the HTS processes required for the beamforming application, large area deposition, HTS compatible resistor process, dielectric film development for HTS overlay connections and ferroelectric phase shifters. The second task developed a number of components, including a broadband 900 hybrid, a power splitter, a broadband phase shifter, and a beamforming network. The final task developed cryogenic packaging techniques and demonstrated a component (a phase shifter) on a cryocooler.
