Abstract
An RF power combiner functioning as a higher-order harmonics filter comprises: at least one pair of coaxially arranged disc-shaped metal conductors, at least one of the conductors having a central axial opening to accommodate a waveguide is provided. Facing surfaces of the disk-shaped metal conductors are shaped symmetrically with respect to the plane of symmetry of the disk-shaped metal conductors to form a plurality of consecutive, radially communicating concentric cavities having isosceles trapezoids with different bases in section. The smaller base of each trapezoid disposed closer to the central axis. The number of the concentric cavities is (2 k+1), where K is the number of signal harmonics being filtered.
