    Abstract: A duplexer/diplexer comprising at least a transmission branch and a reception branch. The transmission branch and the reception branch are modularly connected by shielding, and are arranged such that the two branches are matched to an identical value of resistance (50 Ohms) in their passband, and offer broadband high-impedance in the stopband of the band neighboring the passband. As a result, all three ports of the duplexer/diplexer are matched to the same value of resistance given parallel connection of the two branches.

    Abstract: A ceramic resonator for microwave ceramic filters includes a ceramic body having a predetermined form with surfaces and edges. The ceramic body has an internal conductor bore formed therein and is metallized on all of the surfaces except for at least one at least partially unmetallized surface. One of the surfaces has an aperture window formed therein for coupling to other ceramic resonators to form a microwave ceramic filter. At least one of the edges has a chamfer formed thereon.

    Abstract: A method for soldering a ceramic body of an electric component, such as a microwave resonator, into a metal housing, includes applying a tin layer over the ceramic body provided with an electrically conductive layer. A high-melting-point lead-tin passivation layer is applied to a surface of the housing to be soldered to the ceramic body.

    Abstract: An electrical component with a filter circuit is specified that includes a first bandstop filter and a second bandstop filter. The first bandstop filter includes at least one resonator operating with acoustic waves and has a first stop band. The second bandstop filter includes LC elements and has a second stop band that lies at least one octave higher than the first stop band.
