Abstract
The invention relates to a high-frequency filter comprising a block-like housing ( ) made of a dielectric material, the housing comprising ends ( ) and side surfaces ( ), the section between the ends being provided with a conductive plating ( ) acting as the filter's outer conductor ( ). In addition, the filter comprises at least two holes ( ) extending on the section between the ends of the block-like housing, the holes being plated with a conductive plating to provide two inner conductors ( ). The filter further comprises a connection base ( ) provided with a conductive pattern ( ), the block-like housing being arranged onto the base, and the conductive pattern ( ) of the filter comprising connecting areas ( ) for connecting the inner conductors ( ) onto the connection base ( ). According to the idea of the invention, the filter, which is connected to the conductive pattern ( ) of the connection base ( ), the connection base ( ) being outside the conductive plating ( ) acting as the filter's outer conductor ( ) and arranged on the surface of its block-like housing ( ), comprises one or more coupling members ( ) for setting capacitive couplings between the inner conductors.
