In a wave guide resonant cavity (CAR) formed of f.i. six walls, at least one of which (PE (2)) carries input and output connectors (CON. I, CON.U) and coupling loops (LO), a variable capacity (Cv) is created by displacement of a nucleus or wedge (Cu) on a rodshaped support (AS) which extends along the cavity whole major axis and is free to expand at one end (PE (1)). The maximum value of capacity (Cv) is reached at the maximum displacement of the wedge (Cu) towards said wall (PE(2)) carrying connectors and loops.
