Abstract
A device comprises at the input a first component (PA) having a first output impedance (Z), at the output a second component (ANT) having a second input impedance (Z), and an impedance-matching network between said first and second components. Because the first and/or the second impedance vary/varies, said impedance-matching network comprises a filter (F), with an impedance that is matchable to the first and second impedances, located between said first and second components and comprising at least two acoustic wave coupled resonators. At least one of the resonators comprises a perovskite type material and means for applying a voltage to said resonator, which enable the permittivity and the impedance thereof to be varied.
