The utility model relates to a tunable E face wave filter of high Q value, including first empty waveguide and the empty waveguide of second inserted the metallic diaphragm between first empty waveguide and the empty waveguide of second the empty waveguide facial make -up of first empty waveguide or second is equipped with two or above tuner, wherein, the tuner is the dumbbell shape, and the tuner includes screw and debugging thread plate, the debugging mounting hole of seting up is passed to screw one end in first empty waveguide or the empty waveguide of second, the screw other end is fixed in first empty waveguide or the empty waveguide of second through debugging thread plate. Consequently, the utility model discloses can accurate debugging filter pass band, reduce the filter pass band decay or avoid the filter pass band distortion, its degree of adaptability is high, is favorable to popularizing and applying. Adopt the utility model discloses the device has shortened the wave filter development time and
