Most surface wave filters use interdigital transducers on piezoelectric substates to produce chirp filters. Alternate type of filter use controlled reflection of surface waves from surface gratings. The second type (RAC - Reflective Array Compressor) are free of spurious signal and second order effects, and in large time-bandwith application are better than filter based on interdigital transduces. Designing method, technology and practical results of RAC filter with two 90 degree reflections are presented.
