Abstract:
An impedance matching circuit includes a conductor line having an input port and an output port, a ground conductor, a tunable dielectric material positioned between a first section of the conductor line and the ground conductor, a non-tunable dielectric material positioned between a second section of the conductor line and the ground conductor, and means for applying a DC voltage between the conductor line and the ground conductor. The impedance matching circuit may alternatively include a first planar ground conductor, a second planar ground conductor, a strip conductor having an input port and an output port, and positioned between the first and second planar ground conductors to define first and second gaps, the first gap being positioned between the strip conductor and the first planar ground conductor and the second gap being positioned between the strip conductor and the second planar ground conductor. A non-tunable dielectric material supports the first and second planar ground conductors and the strip conductor in the same plane. A connection is provided for applying a DC voltage between the strip conductor and the first and second planar ground conductors. A plurality of tunable dielectric layer sections are positioned between the strip conductor and the first and second planar ground conductors so as to bridge the gaps between the said first and second planar ground conductors and the strip conductor at a plurality of locations, leaving non-bridged sections in between, defining a plurality of alternating bridged and non-bridged co-planar waveguide sections.

Abstract:
A variable impedance circuit includes a matching network for coupling to a tunable device, where the matching network has a first port and a second port, where the tunable device is coupled to one of the first port or the second port, and where the matching network has one or more variable dielectric capacitors. The one or more variable dielectric capacitors can be operable to receive a first of one or more variable voltage signals to cause the one or more variable dielectric capacitors to change a first impedance of the matching network. The tunable device can be operable to receive a second of one or more variable voltage signals to cause a change in a second impedance of the tunable device.

An impedance matching circuit includes a matching network for coupling to a variable load, where the matching network has a first port and a second port, and where the variable load is coupled to one of the first port or the second port. The matching network can have one or more variable dielectric capacitors, where the one or more variable dielectric capacitors are operable to receive one or more variable voltage signals to cause the one or more variable dielectric capacitors to change an impedance of the matching network, and where the change in the impedance of the matching network causes an increase in power transferred from the first port to the second port or from the second port to the first port.
