RF power combiner which functions as a high-order harmonic filter

摘要

RF power combiner which functions as a high-order harmonic filter, the center for accommodating the waveguide at least one set of axes opening at least one coaxially disposed with difference disk-like metal conductors. Surface opposite of said disc-shaped metal conductors, a plurality said the symmetry plane of the disc-shaped metal conductors are formed so that a symmetric, with a isosceles trapezoid with a different base in the cross section, and communicates continuously and radially It will form a concentric cavity. The base of the trapezoid is placed closer to the central axis is shorter base. The number of the concentric cavity, (2k + 1) is, k is the number of signal harmonics are filtered. All of concentric cavities of said plurality of cavities is a different angles in the same radiation length and the trapezoid base, the angle that depends on the wave impedance of a segment of a radial transmission line formed by each of the concentric cavity, the with. RF power combiner includes a plurality of horn antennas which are uniformly disposed about the periphery of said disc-like metal conductors. Outer edges of the horn antenna is adapted to connect the RF module is the source of the RF signal.BACKGROUND 1
