Title

Design Of Saw Fir Filters For Quadrature Binary Modulators

Abstract

SAW filters are ideally suited for quadrature binary modulation systems since precise time domain responses can be achieved. In addition, SAW filter designs can often compensate for system implementation distortion such as spectral rolloff or matching. This yields near ideal time and frequency domain responses. Finally, it is relatively easy to implement any FIR response for the required system. The design approaches for several standard modulator filters, such as QPSK and MSK, as well as several newly developed FIR modulator filters will be compared in this paper. The design procedures, including zero extraction, are discussed. Experimental and theoretical results for several different SAW filter modulator designs are presented and show excellent time and frequency domain correlation.
