Abstract: A tunable filter comprises at least two resonator circuits placed between two matching networks characterized in that: one resonator is connected at a first of its ends to the ground plane M of the filter by metallized holes and at a second end to a MEMS network; the distance between the two resonators forms an inter-resonator inductive coupling circuit; an inter-resonator coupling capacitor is formed by two etched lines 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 resonator and the ground plane M by means of metallized holes; and the filter comprises a number of independent electrical control voltages designed to actuate the MEMS.
