Systems Applications of SAW Filters and Delay Lines.

Abstract

This paper reviews the applications that SAW (Surface Acoustic Wave) filters and delay lines have to communications and radar systems. The development of SAW resonators at frequencies up to 1 GHz is reported together with their promise for stabilizing precision oscillators. Such oscillators could be useful, for example, as clocks for CCDs. Operation directly at 1 GHz eliminates the multiplier chains required for conventional quartz oscillators. The use of miniature SAW transversal filters for banks of contiguous filters is shown to be important in reducing the size of fast frequency synthesizers and multiplexers for spread spectrum communications applications. The design of a 9.1 micron sec delay line with all spurious echoes 70 dB down is described together with its radar signal processing application. (Author)
