Abstract :
A dispersive delay line (DDL) with a dispersive interdigital transducer (having variable spaced fingers) and with a simple periodic transducer is examined. The possibility to obtain higher band of the DDL in a case of its specific configuration being a nonperiodic electrodes structure of the dispersive transducer is described. Experimental results of the research for chosen parameters of the DDL at a fundamental and higher bands are presented in the paper.
