Abstract: An exemplary semiconductor technology implemented microwave filter includes a dielectric substrate with metal traces on one surface that function as frequency selective circuits and reference ground. Other metal traces on the other surface of the substrate also provide reference ground. Bottom and top enclosures that enclose the substrate have respective interior recesses with deposited continuous metal coatings. A plurality of metal bonding bumps or bonding wall extends outwardly from the projecting walls of the bottom and top enclosures. The bonding bumps on the bottom and top enclosures engage reference ground metal traces on respective surfaces of the substrate. As a result of applied pressure, the bonding bumps and respective reference ground metal traces together with the through-substrate vias form a metal-to-metal singly-connected ground reference structure for the entire circuitry.

Abstract: An exemplary electronic assembly includes a planar semiconductor substrate having a front side with semiconductor components and a back side that includes one recess extending inwardly. One of an isolator and circulator is formed as part of the planar semiconductor substrate and includes one magnetic ferrite disk mounted within the one recess within the thickness of the planar semiconductor substrate. The one of an isolator and circulator has at least input and output ports. The input port is disposed to receive a radio frequency signal to be coupled with low insertion loss to the output port while providing high insertion loss to other radio frequency signals attempting to propagate from the output port to the input port.

Abstract: One example includes an integrated circulator system comprising a junction. The junction includes a first port, a second port, and a third port. The junction also includes a substrate material layer on which the first, second, and third ports are provided. The junction also includes a magnetic material layer coupled to the substrate layer. The junction further includes a resonator coupled to the first, second, and third ports to provide signal transmission from the first port to the second port and from the second port to the third port based on a magnetic field provided by the magnetic material layer.
