Abstract
An embodiment of the present invention provides an apparatus, comprising a tunable filter with a plurality of bond wires connecting voltage tunable dielectric capacitors to an RF ground and serving as inductors, wherein inductive coupling between the plurality of bond wires serve as coupling between resonators within the tunable filter. The voltage tunable dielectric capacitors may be integrated onto a single MgO chip thereby providing a complete set of tunable capacitors for a filter circuit in a low cost, compact package.
