Abstract (en)
[origin: FR2755544A1] The invention concerns a filtering device comprising a metal cavity (1, 11) closed by two end walls (3a, 3b; 13a, 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, characterised in that it comprises at least one coupling iris (7a, 7b; 17) which also extends transversely relative to said axis.
