Novel Ferroelectric Materials for Satellite Communications

Abstract

This report summarizes work performed by DuPont and the University of Colorado. The work was divided into seven key task areas: (1) Large Area Sputtered Film Manufacturing for Cryogenic Temperature, (2) Large Area Sputtered Film Manufacturing for Ambient Temperature, (3) Multilayer Film Development and Manufacturing, (4) Exploratory Laser Ablation Processing (University of Colorado), (5) Materials Discovery Research, (6) Rapid Test Method Development, and (7) Demonstration Device Design and Test. A wide range of ferroelectric materials and related compounds were explored for use in tunable microwave devices: the best figures of merit of thin films for cryogenic operation were in the range 15-20; the best results for room temperature were lower, generally less than 5. Tunable filters and devices were designed which frequency tunabilities in the range of 5-10% with low 0.
