Abstract : This application describes a broad bandwidth surface acoustic wave filter utilizing two broadband surface acoustic wave transducer pairs which individually comprise a single input and output. One pair of broadband surface acoustic wave (SAW) transducers is offset in frequency from a second pair of broadband SAW transducers. Each transducers is tuned with a single series inductor, and then both channels are connected electrically in parallel. The low frequency pair of transducers is tuned for maximum response below their synchronous frequency, and the high frequency pair of transducers is tuned for maximum response above their synchronous frequency.
