Flat Passband Etched Groove SAW (Surface Acoustic Wave) Filter.
Abstract
An acoustic surface wave device is configured as a bandpass filter. The device employs two interdigital transducer pairs for input and output. Each transducer pair has a slant finger geometry. The fingers are electrodeposited into grooves etched into the substrate. The grooves enhance the electromechanical coupling of high frequency components and thus provide a flatter amplitude response curve. (Author).
