Abstract
An electronic device comprises a non-metallic waveguide, a tunable component mounted within the waveguide, and a conductive layer on a surface of the waveguide. The tunable component can comprise a tunable filter. The non-metallic waveguide can comprise a plastic material. Connections for applying a tuning voltage to the tunable component can be provided. A temperature sensor can be connected to the waveguide.
Claims15
An electronic device comprising:
- a non-metallic waveguide;
- a tunable filter mounted within the waveguide, said tunable filter including a tunable capacitor and wherein said tunable capacitor comprises a layer of tunable dielectric material;
- said tunable dielectric material operable at least at temperatures that include room temperature and wherein the dielectric constant can be changed by 10% to 80% at 10 V/μm;
- and
- a conductive layer on a surface of the waveguide.
