Through-chip coupling is utilized for signal transport, where an interface is formed between a first coil on a first integrated circuit (IC) chip and a second coil on a second IC chip. The first coil is coupled to an antenna. The second coil is coupled to an amplifier circuit. The second coil is not in direct contact with the first coil. The first coil and the second coil communicatively transmit signals between the antenna and the first amplifier circuit.

A bandpass filter comprises a first capacitor, a second capacitor, a third capacitor and at least two resonators. The first and second capacitors are coupled in parallel with each other, and each of the first and second capacitors includes an input. The third capacitor is coupled between the first capacitor and the second capacitor at their respective inputs. The at least two resonators are coupled in parallel with the first capacitor and the second capacitor and are positioned adjacent to each other at a distance such that the at least one component of the resonators are electromagnetically coupled together to provide three (3) transmission zeros.

A multi-chip module includes a chip stack package including at least one pair of stacked dies, the dies having overlapping opposing faces, and at least one capacitive proximity communication (CPC) interconnect between the pair of stacked dies. The CPC interconnect includes a first capacitor plate at a first one of the overlapping opposing faces and a second capacitor plate at a second one of the overlapping opposing faces spaced from and aligned with the first capacitor plate. The CPC interconnect further includes an inductive element connected in series with the first capacitor plate and second capacitor plate, wherein the capacitor plates form part of a capacitor and the capacitor cooperates with the inductor element to form a LC circuit having a resonant frequency.
