  • Filter and tuning element
    Patent number: 6198363
    Abstract: The invention relates to a filter and a frequency tuning element. The filter comprises a shell construction (2a to 2d) of conductive material with at least one section (14 to 16) and in the shell construction (2a to 2d) at least one resonator (17 to 19) of conductive material in said at least one section (14 to 16) for forming at least one resonance circuit (11 to 13). In the filter (1) the resonator (18) comprises as its extreme ends a base (18a) and a second end (18b), in said filter (1) the base (18a) of the resonator (18) being fastened to the shell construction (2a to 2d) and the second end (18b) of the resonator (18) being directed elsewhere towards the shell construction (2a to 2d) at a distance therefrom, the resonator (18) comprising a means (32) which directs its surface towards the shell construction (2a to 2d) and increases the cross-sectional area of the resonator to increase the capacitance between the resonator (18) and the shell construction (2a to 2d).

  • Integral resonators for a filter and a method for manufacturing thereof
    Patent number: 5892419
    Abstract: The invention relates to a filter, a method for manufacturing a filter, a resonator construction, and a method for manufacturing a resonator construction. The filter comprises a shell construction and a plurality of resonators mounted in the shell construction for forming a multi-circuit filter. The filter comprises a connecting portion which combines the resonators and is integral with the resonators.

  • Filter
    Patent number: 5874872
    Abstract: A filter has a shell construction including a connection surface and a bar-like resonator in the shell construction. The bar-like resonator has an initial section having one end region thereof connected to the connection surface of the shell construction and an opposite end region. A substantially straight and elogate intermediate section extends from the opposite end region of the initial section to an end and a turning-point section extends from the end of the intermediate section to an end. A substantially straight and elongate end section has one end connected to the end of the turning-point section so as to extend adjacent to the intermediate section and supporting means connect to the connection surface of the shell construction for supporting the bar-like reasonator at least at one of the end section and turning-point.
