FIELD: SHF technology. SUBSTANCE: ladder-type rejection filter has section 1 of strip transmission line, inductive and capacitive elements 2 and 3, gyromagnetic resonators 4 and magnetic system with pole pieces. Minimal number of resonators in filter equals 2 and maximum number may exceed 3 due to increase of number n of grounded partitions 7 inserted in symmetry and matched at angle α = 2π/n for separation of resonators 4 from each other. Direct interaction between resonators 4 is avoided by insertion of additional sections 6. EFFECT: increased rejection with simultaneous decrease of dimensions. 2 dwg
