Abstract
An apparatus includes a top conductive layer of on an integrated circuit waveguide filter and a bottom conductive layer. The top and bottom conductive layers are coupled via a plurality of couplers that form an outline of the waveguide filter. A dielectric substrate layer is disposed between the top conductive layer and the bottom conductive layer of the integrated circuit waveguide filter. The dielectric substrate layer has a relative permittivity, εr that affects the tuning of the integrated circuit waveguide filter. At least one tunable via includes a tunable material disposed within the dielectric substrate layer and is coupled to a set of electrodes. The set of electrodes enable a voltage to be applied to the tunable material within the tunable via to change the relative permittivity of the dielectric substrate layer and to enable tuning the frequency characteristics of the integrated circuit waveguide filter.
