摘要： The invention relates to a tractable filter comprising at least two resonating circuits (14a, 14b) arranged between two matching networks (4, 5), characterized in that: one resonator is connected, by a first of the ends thereof (14a
1 , 14b
1 ), to the ground M of the filter by plated through-holes (16), and by a second end (14a
2 , 14b
2 ) thereof to a MEMS network (12); the distance d between the two resonators forms an inductive inter-resonator coupling circuit (10); an inter-resonator coupling capacitor (11) is formed by two etched lines (11a, 11b) connected to the first and second resonators; the MEMS networks are distributed around the ends of the resonators; the MEMS networks are connected between the first and second resonators and the ground M by means of plated through-holes; and the filter includes a plurality of independent control voltages Vi (17) designed to operate the MEMS.
