Abstract

A time delay filter comprising a substrate comprising a first surface and a second surface opposite the first surface; a first LC resonator coupled to the substrate and comprising a first coupling point, a first capacitive element electrically coupled between the first coupling point and the first conductive region, and a first inductive element coupled between the first coupling point and the first conductive region, and comprising a first and second inductor tap; and a second LC resonator coupled to the substrate and comprising a second coupling point, a second capacitive element electrically coupled between the second coupling point and the first conductive region, and a second inductive element electrically coupled between the second coupling point and the first conductive region wherein the system group delays a signal output at a second coupling point relative to a signal input at the first coupling point.
