Novel Cryogenic Dielectric Resonator Devices for Satellite Communication
Ongoing progress in manufacturing dielectric ceramics and single crystals with high dielectric constant and low microwave losses has turned out to be a challenge for the development of novel devices for satellite communication. From this development device performance is expected to benefit for possible device operation temperatures ranging from cryogenic temperatures around 50 — 150 K (achievable with one-stage close cycle refrigerators) over temperatures from 150 to 20OK (in principal achievable with radiation cooling) towards room temperature, if novel dielectric resonator structures with lower loss contribution of the metallic housing would become available.
