Abstract
TV signal distribution filter device which includes at least one tuneable band-pass filter circuit, each tuneable filter circuit having a signal input for receiving a TV signal, a signal output for delivering a filtered TV signal, and a plurality of components connected in a predetermined configuration between the signal input and the signal output and together being provided for filtering the received TV signal to the filtered TV signal, said plurality of components including at least a first inductor and a second inductor, each accompanied by a tuneable capacitive component and connected to a voltage node which is provided for receiving a tuning voltage for tuning the tuneable capacitive component and thereby setting a filtering parameter of the tuneable filter circuit, the first and second inductors being planar inductors which are mechanically fixed and embedded in a dielectric environment and are electro-magnetically coupled with each other.
