High-frequency circuit including a circuit board and a waveguide structure

A high-frequency circuit comprising:

• a circuit board which bears, over a plane of the circuit board, at least one electronic component and a conductor structure;
• and
• a waveguide structure manufactured separately from the circuit board, which is positioned on the circuit board in such a way that high-frequency signals are transferable between the conductor structure on the circuit board and the waveguide structure;
• wherein:
• the waveguide structure forms a coupling dome in which a coupling channel extends at a right angle to the plane of the circuit board;
• the conductor structure forms a launcher on the circuit board for the coupling channel;
• the launcher is positioned inside an outline of the coupling channel;
• and
• the circuit board is pre-tensioned locally against the coupling dome by a spring at a point of each coupling dome.

A high-frequency circuit comprising:

• a circuit board on a plane of which at least one electronic component is arranged;
• and
• a waveguide structure manufactured separately from the circuit board, which is positioned on, and facing the plane of, the circuit board in such a way that high-frequency signals are transferable between the electronic component and the waveguide structure;
• wherein:
• the waveguide structure is held on the circuit board using press-fit pins formed in one piece with a metal plate which bears the waveguide structure;
• and
• launchers for coupling in the high-frequency signal into the waveguide structure are integrated into the electronic component with respective channels extending from the electronic component in a direction perpendicular to the plane of the circuit board towards the waveguide structure for transfer of signals of the electronic component from the launchers into the waveguide structure through the channels.
