Architecture of a multifrequency synthesizer with a high spectral efficiency on the basis of a dispersive surface-acoustic-wave filter

New possibilities of creating a wideband parallel multifrequency synthesizer with a high spectral efficiency are investigated. The synthesizer is based on a dispersive filter using surface acoustic waves (SAWs). Discrete spectrally distinguishable frequencies are synthesized with the help of derived...

Zusammenfassung:New possibilities of creating a wideband parallel multifrequency synthesizer with a high spectral efficiency are investigated. The synthesizer is based on a dispersive filter using surface acoustic waves (SAWs). Discrete spectrally distinguishable frequencies are synthesized with the help of derived theoretical relationships. SAW-based synthesizer characteristics (bandwidths, the number of carrier frequencies generated, frequency pulse durations, and efficiency parameters) have been analyzed.
