Elastic wave device

Abstract

The invention relates to an elastic wave device in the field of elastic wave-based components for fields such as telecommunications. The device of the invention comprises a first electromechanical device, in particular a transducer 3, and a second electromechanical device, in particular a transducer 5; an array of at least one electrode 4000 located between the first transducer 3 and the second transducer 5 in the direction of propagation of the elastic waves, at least one electrode of which is connected to a predetermined electrical potential 1005, 2005, 3005 via a variable impedance 1003, 2003, 3003; and a control means 1007, 2007, 3007 for modifying the variable impedance 1003, 2003, 3003.
