Abstract: The present invention relates to a transmission line to waveguide transition arrangement comprising a dielectric carrier material arrangement having a first main side and a second main side, the arrangement comprising a transition portion with an opening, having at least one edge and an electrically conducting border which follows the opening and is electrically connected to a ground metalization on the second main side. A transmission line conductor extends in the dielectric carrier material arrangement towards the border. The arrangement further comprises a transitional part with a border contact section having an outer circumference that essentially follows the border's shape except for a gap dividing the border contact section. The transitional part further comprises a conductor contact section which protrudes from the border contact section through the gap, contacting the end of the transmission line conductor and extending into the opening.

Abstract: A filter device for a printed circuit board, wherein the filter device comprises a selected pattern of conductive material arranged to be electromagnetically coupled to an electrically conductive plane comprised in the printed circuit board. The invention is characterized in that the filter device is a separate unit from the printed circuit board and is connectable to the printed circuit board via first connectors positioned on the filter device and second connectors correspondingly positioned onto the printed circuit board.
