FIELD: microwave engineering. SUBSTANCE: proposed filter has insulating substrate bearing ground base on one side and short-circuited strip conductors that function as resonators, on other side; novelty is that quarter-wave microstrip resonators are separated by means of shielding metal plates and that conductive-inductive coupling between these resonators is effected by lumped inductances, each being soldered at ends to two resonators being coupled. EFFECT: enhanced level of parasitic passband suppression; reduced size of filter. 1 cl, 1 dwg |
