Abstract
A dielectric-based filter includes a thermally insulated housing, at least one filter formed from a dielectric material disposed inside the insulated housing, and a temperature maintenance device having a heating component and a cooling component for maintaining the temperature of the filter inside of the insulated housing within a temperature range. In a preferred aspect of the invention, the temperature maintenance device includes a thermoelectric cooler. The device permits the use of temperature-dependent low loss, high dielectric constant materials in filtering/resonator applications. During operation of the device, the dielectric-based filter is maintained at substantially room temperature.
