Abstract
An electronic structure comprising an electrically conductive base member with a layer of piezoelectric material bonded thereon, characterised in that at least first and second interdigital arrays are bonded or otherwise attached to said layer, in use said first interdigital array relying on the piezoelectric properties of said layer and said second interdigital array relying on the dielectric properties of said layer. Typically the first and second interdigital array forms part of at least one oscillator, such as a surface acoustic wave ('SAW') resonator, a shallow bulk acoustic wave ('SBAW') resonator, or the like. The second interdigital array forms part of at least one directional coupler such as a Lange coupler.
