Abstract: An analog time delay filter circuit including a first delay circuit block arranged in a modular layout, having a first time delay filter, a first input, a first output, and first and second pass-throughs; a second delay circuit block arranged in the same modular layout, having a second time delay filter, a second input, a second output, and third and fourth pass-throughs; and an interposer circuit block that electrically couples the second input to the first pass-through and the second output to the second pass-through.

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.

Abstract: A multilayer fringe capacitor includes first and second interdigitated capacitor electrodes, both parallel to and intersecting a first planar surface; third and fourth interdigitated capacitor electrodes, the first and second electrodes parallel to and separated by a non-zero distance from the third and fourth electrodes; a first set of coupling vias that electrically couples the first electrode to the third electrode; and a second set of coupling vias that electrically couples the second electrode to the fourth electrode.
