Abstract
A method for fabrication of a filter includes forming an input transformer pole in a first substrate by forming a first conductive via, forming an output transformer pole in the first substrate by forming a second conductive via, forming one or more filter poles in the first substrate between the input transformer pole and the output transformer pole by forming one or more conductive vias in the first substrate between the input transformer pole and the output transformer pole, fabricating one or more tuning elements on a second substrate, wherein the number of tuning elements corresponds to the number of filter poles between the input transformer pole and the output transformer pole, and bonding the second substrate to a top surface of the first substrate so that each tuning element on the second substrate is aligned with and overlays a filter pole on the first substrate.
