20150303543 | RADIO-FREQUENCY BLOCKING FILTER - A radio-frequency filter comprises an input terminal and an output terminal. A signal line is galvanically connected or capacitively coupled firstly to the input terminal and secondly to the output terminal. The signal line, with the formation of a capacitive inner conductor and/or resonator coupling, runs past the relevant inner conductor through the resonators of the radio-frequency blocking filter. The signal line has at least one galvanic isolation location in the form of a capacitive isolation location. The capacitive isolation location is spaced apart from the inner conductors and capacitively coupled thereto. The resonators and/or the inner conductors capacitively coupled to the signal line. | 10-22-2015 |
20150288044 | HIGH FREQUENCY FILTER HAVING FREQUENCY STABILIZATION - A temperature-compensated high frequency filter of coaxial construction comprises at least one resonator having an inner conductor and an outer conductor housing. A compensation device made of a second material has a second coefficient of thermal expansion. The compensation device comprises a wall section, which extends in an axial direction and is variable in length in this direction in the event of a temperature change. The wall section is part of the housing wall configured in the manner of an intermediate layer or an upper-most layer located adjacent to the housing cover. The wall section may extend in an axial direction or in a direction transversely thereto and be variable in length in this direction in the event of a temperature change. The wall section is an integral part of the housing cover or is connected to the housing cover, or forms the housing cover having convex outwardly directed curvature. | 10-08-2015 |
