Abstract
The structure of a frequency synthesizer for acoustic waves includes an input narrow band transducer in its input arm for receiving an input electric signal at an input frequency, a wide band transducer in its output arm for supplying an output signal; and a perforated region formed of a two dimensional array of cavities disposed between the first and second arms. The first arm contains multiple metal fingers, disposed perpendicular to the first arm and spaced apart from one another at a distance of the wavelength of the input signal to ensure acoustic excitation in the first arm at the input frequency. The second arm contains a single finger to accommodate a non-linear output signal oscillating at a harmonic of the first frequency. The frequency synthesizer can be patterned in aluminum nitride (AlN) in a silicon substrate.
