Abstract
A power device comprises an output port and at least one first acoustic pathway and one second acoustic pathway, each acoustic pathway comprising at least one first input acoustic wave transducer connected to an input port, and an output acoustic wave transducer connected to the output port. Each acoustic pathway further comprises a floating acoustic wave transducer connected to a floating port; the input transducer and the output transducer being separated by a distance equal to (2m+1)λ/4 with m an integer and λ the propagation wavelength; the input transducer and the floating transducer being separated by a distance equal to (2n+1) λ/2 with n an integer; each output transducer being connected to the output port, said power device being a combiner.
