A filter device including a metal cavity (1, 11) closed by two end walls (3a, 3b; 13, 13b) extending transversely relative to the axis of said cavity (1, 11) and at least two dielectric inserts (4a, 4b; 14a to 14d) defining a resonator (5, 15a, 15b) in said cavity, characterized in that it includes at least one coupling iris (7a, 7b; 17) which also extends transversely relative to said axis.
