ABSTRACT:
A strip coupled type convolver includes an aluminum nitride (AlN) layer and a semiconductor layer both provided on a single sapphire substrate, and includes many metal strips extending across a surface wave propagating path on a surface of the AlN piezoelectric layer to transmit a potential on the piezoelectric surface to a Schottky diode array provided on the semiconductor surface to cause a nonlinear interaction.
