A wideband signal generation and processing device based on surface acoustic wave (SAW) technology was reported.Direct acoustic coupled structure using phase reversion transducer(PRT) and dispersive interdigital transducer (DIDT) was innovatively adopted. Under 25% large relative bandwidth,the high compression main side lobe ratio was 35 dB,the insertion loss was 34 dB,which could well meet the system requirement.
