Abstract: The present disclosure relates to transverse magnetic wave (TM) mode filters and methods for manufacturing a TM mode filter. One example TM mode filter includes a filter body, a dielectric, and a transition layer, the filter body including a filter cavity and a cover, and having hollow confined space, the dielectric located in the hollow confined space, and the transition layer configured to connect the dielectric and the filter body. A coefficient of thermal expansion (CTE) of the transition layer is between a CTE of the filter body and a CTE of the dielectric.

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: Provided is a microwave filter system having a feedback structure. The microwave filter system may include an input hybrid coupler configured to output first output signals having a phase difference with respect to an input signal; filters disposed to be in parallel with an output end of the input hybrid coupler, and configured to filter the first output signals; and an output hybrid coupler configured to output second output signals having a phase difference with respect to each of signals filtered through the filters. An output signal of the output hybrid coupler is applied to an input end of the input hybrid coupler along a feedback path.
