    Abstract: A composite resonator includes a first resonator extending in a first plane direction, a second resonator spaced apart from the first resonator in a first direction and extending in the first plane direction, a third resonator located between the first resonator and the second resonator in the first direction and configured to be magnetically or capacitively connected to or electrically connected to each of the first resonator and the second resonator, and a reference conductor extending in the first plane direction, located between the first resonator and the second resonator in the first direction and serving as a potential reference of the first resonator and the second resonator.

    Abstract: A waveguide transition includes a ridge waveguide section with a first ridge part running along a first wall having a first distance to an opposing second wall. The waveguide transition comprises a partial H-plane waveguide section with an electrically conducting foil that comprises a longitudinally running foil slot ending a certain edge distance before a foil edge that faces the ridge waveguide section. The ridge waveguide section and the partial H-plane waveguide section overlap during a transition section that has a first end at a transition between the second wall and a third wall. There is a second distance between the first wall and the third wall that exceeds the first distance. The transition section has a second end where the first ridge part ends by a transversely running second ridge part that crosses the foil slot and connects to a third wall.

    Abstract: An RF filter includes: an electrical conductor defining an outer sphere; a dielectric material defining an inner sphere disposed within the conductor outer sphere; and at least a first electrical probe and a second electrical probe. Each probe extends through the conductor and is electrically insulated from it. A spherical shape of one or both of the inner and outer spheres is interrupted by: a) a first localized discontinuity in said spherical shape disposed along a first axis passing through a geometric center of the one or both of the inner and outer spheres; and b) a second localized discontinuity in said sphere form disposed along a second axis passing through the geometric center, the second axis perpendicular to the first axis. There can be more than these two discontinuities, implemented as chamfers, tuning screws, and the like. Series and parallel coupling of the spheres is detailed.

    Abstract: The tunable bandpass filter is used for filtering an electromagnetic signal, has a system passband between a first and a second tunable cutoff frequencies, and has a first subfilter and a second subfilter connected to one another in series between an input port and an output port and being complementary to one another in the tunable bandpass filter. At least one of the first subfilter and the second subfilter being connected to operate in reflection.
