Abstract: The invention relates to a microwave ceramic filter with an improved edge steepness. Said filter comprises at least two resonators (2, 3) in a one-piece ceramic body (1) and coupling structures (6, 7) associated to said resonators (2, 3) for capacitively coupling the ceramic filter to an external H.F. circuit. At least one corresponding oscillator (10, 13) is guided in parallel to the resonators (2, 3) in the ceramic body (1).

Abstract: The invention relates to a duplexer, which is constructed from ceramic microwave resonators and whose ceramic base body is provided with a metallic shielding structure. Said structure comprises at least one end plate that is provided over the end face of the base body, an upper shielding bracket and at least one lower shielding bracket. The shielding brackets run on the surface of the base body in corresponding recesses and lie flush with the remaining surface of the ceramic base body. This allows a low-rise construction to be achieved whilst maintaining the same electrical characteristics.

Abstract: The aim of the invention is to integrate an LTCC balun in the microwave ceramic body of a duplexer without increasing the total height of said duplexer. To achieve this, the height of the ceramic body in the vicinity of the RX filter is reduced to a surface area that corresponds to the size of the LTCC balun. A compact component, which can deliver a symmetrical output signal for the RX path without a volume increase, is thus obtained without modification to the characteristics of the TX filter.
Abstract translation: 本发明的目的是在不增加所述双工器的总高度的情况下将LTCC平衡 - 不平衡转换器集成在双工器的微波陶瓷体中。 为此,将RX滤波器附近的陶瓷体的高度减小到与LTCC平衡 - 不平衡转换器的尺寸相对应的表面积。 因此,可以在不改变TX滤波器的特性的情况下获得紧凑的组件,其可以为RX路径提供对称的输出信号而不增加音量。

Abstract: The invention relates to a duplexer/diplexer comprised of at least one transmitting branch (1) and of at least one receiving branch (2). The transmitting branch (1) and the receiving branch (2) are modularly connected by a shielding (3) and are arranged such that both branches, in the passband thereof, are adjusted to an identical value of resistance (50 Ohms) and are highly resistive, with regard to broad-band, in the stop band of the band adjacent to each passband. As a result, all three ports of the duplexer/diplexer are adjusted to the same value of resistance when both branches (1, 2) are connected in parallel.

Abstract: The invention relates to a component arrangement in which an electrical component (5) is sunk into a recess (4) of a printed circuit board (1), said electrical component (5) being fixed to an auxiliary printed circuit board (6) which, in turn, is connected to the printed circuit board (1). By sinking the electrical component (5) into the recess (4) of the printed circuit board (4), the amount by which the component projects (U) is advantageously reduced.
