Temperature stable low loss ceramics for resonators and filters — •Ian Reaney — Materials Science and Engineering, University of Sheffield, Sheffield, UK

Micro wave (MW) dielectric ceramics are required to be temperature stable and have a low dielectric loss to prevent heating of the sample when operated at or near resonance. They are used in many applications but specifically in this contribution the use of MW dielectric ceramics as resonators, filters and antennas is considered. The relevant technologies for these application are reviewed along with their selective materials parameters. The underpinning crystal chemistry that leads to optimisation of properties is also reviewed and some new materials and novel processing routes to improve device performance are discussed.
