ABSTRACT:
The invention concerns acoustic surface wave devices with multistrip couplers. The coupler of such a device comprises two arrays of N conductive strips connected by a connecting array and having at least one characteristic, such as for example their periodicity which is distinct for the two arrays. In modifying, for example, the ratio p.sub.1 /p.sub.2 of the periodicities of the arrays, the operation of this device is modified. This device permits in particular the construction, for wide frequency bands of utilisation of n dB couplers, energy concentrators or unidirectional transducers.
