TUNING ARRANGEMENT

摘要

The present invention relates to a tuning arrangement for combiner filters which include a dielectric waveguide resonator (3) and a tuning capacitance (4) coacting therewith. According to the invention, the tuning capacitance (4) has the form of a substantially isosceles acute-angled triangle bent to a circularcylindrical form with the cylinder axis parallel with the waveguide resonator (4). The apex of the triangle is attached to the centre of the opposing side. The cylindrical tuning capacitance (4) can be rotated around the cylinder axis, for tuning the combiner filter.
