Embodiment Construction

[0024] Referring to the drawings, an RF filter F is disclosed which may be used in connection or coupling with an RF device such as a transmitter, receiver, transceiver or amplifier. For example, the RF device may be a radio unit in a cellular radio network or a module therein.

[0025] The filter F has signal ports SP1, SP2 to which connection can be made by cables connecting the filter F to an antenna and eg a transceiver. image 3 A short cable for the signal ports SP1, SP2 shown in , can connect the filter to a coaxial connector mounted on the wall of an outer housing (not shown) surrounding the filter.

[0026] The filter comprises a housing structure C having a wall structure W, a bottom B below the wall structure and a cover T on top of the wall structure. The housing structure C (ie its wall structure W, bottom B and lid T) is made of a conductive metal such as copper or aluminum coated eg with silver or other metals to improve conductivity.

[0027] The RF filter sh...

Abstract

The invention relates to an RF filter comprising a casing (C), a wall structure (W) between a bottom (B) and cover (T) of which defines inside of it at least one compartment (CPA1-CPA4). The RF filter has compartment-specific resonators (R1-R4), and the RF filter comprises a signal port (SP1) and an RF transmission line (TL) connected to it, the RF transmission line being arranged to transfer an RF signal to the compartments (CPA1-CPA4) of the RF fil-ter. In order to support the RF transmission line, the wall structure (W) of the casing (C) comprises one or more supporting brackets (SU1-SU4, SU11-SU13) which are bent from a wall of the wall structure and to which the transmission line (TL) is fixed by means of an insulating mounting (IS).

Description

technical field [0001] The present invention relates to an RF filter. Background technique [0002] RF filters (ie radio frequency filters) are used as filtering and matching circuits in connection with RF equipment such as transmitters, receivers or transceivers, in particular amplifiers in RF equipment, eg in base stations of mobile telephone networks. [0003] A filter of the resonator type comprises a housing structure with one or more compartments whose shape is defined by the wall structure of the housing. [0004] Typically, the compartments of the housing structure may include an inner conductor (known as a resonator or resonator rod) attached to the bottom of the compartment or cavity, as a common structure for coaxial resonators, wherein the inner conductor or resonant The device shares a common axis, ie coaxial, with the surrounding compartments or cavities. The compartments in the metal housing together with the metal inner conductor in the housing form a reson...
