Abstract

The invention relates to a cavity filter for electromagnetic waves. The cavity filter comprises a first casing element (2) and a second casing element (3), which together define a cavity (1), a tuner (11) of dielectric material and a resonator (8) of dielectric material, which resonator is provided with a through-hole to allow the tuner to move at least partially inside the resonator. The resonator is held stationary in the cavity by means of a tube-shaped first support (9) on a first side of the resonator and a tube-shaped second support (10) on a second side of the resonator. The first support is in contact with the resonator at a first contact surface (24), which is adjacent to a first centring surface (25) at an angle to the first contact surface. The second support is in contact with the resonator at a second contact surface (26), which is adjacent to a second centring surface (27) which is at an angle to the second contact surface. The invention also relates to the resonator and a method for assembling the cavity filter.
