Surface acoustic wave devices incorporating ion beam-etched reflective grating structures were designed and constructed to expand and compress a wideband, low dispersion chrip signal. Hamming weighting was incorporated in the compressor. Bandwidth was 200 MHz, dispersive time was 0.5 microsec, and center frequency was 685 MHz. A new concept called TRAC for Tilted Reflective Array Compressor was used primarily because the low dispersion would cause high insertion loss with standard designs. Special techniques to achieve the required nonuniform groove depth profile and remove the ion beam-caused surface damage layer were developed. Although most performance requirements of the devices were met, the best case sidelobe suppression was predicted to be only about 24 dB instead of the goal of 40 dB.
