<p>The flexural-mode electromechanical filter has parallel rod-shaped resonators connected by wires and lying in the same plane. Electrostrictive transducers are coupled to the input and output of the chain of resonators. The vibration nodes (11, 11') of adjacent resonators (2, 4 and 5, 7) are joined by coupling elements (3, 6) lying parallel to the long axis of the filter and on the same side of it. Two extra couplings (10, 10') bridge the aforementioned coupling elements along the long axis of the filter at antinodes.</p> |
