摘要: A relatively narrow fractional bandwidth saw filter formed on a standard ST cut of quartz. The electrode pattern is modified in order to eliminate distortion. In particular, the overlap with one or less active overlaps per wavelength those regions SAW where weighing function maximum. plurality six finger/λ patterns two also provided.
