SAW filter technology and applications
Abstract
Surface Acoustic Wave (SAW) filter technology has been employed in a number of systems applications. These filters range in frequency from about 30 MHz to as high as 2 GHz. Loss as low as .6 dB has been achieved at 35 MHz and 4.5 dB at 1233 MHz. Narrowband filters utilizing St-Quartz as a substrate will be discussed along with medium and wideband devices constructed on lithium niobate. A variety of transducer technology will be presented which includes narrow-bandwidth three phase unidirectional transducers, medium bandwidth apodized three phase unidirectional transducers and very flat frequency response wideband slanted array transducers.
