Surface acoustic wave filter and communication apparatus with the same

A surface acoustic wave filter, comprising:

• a piezoelectric substrate;
• and
• at least a first and a second filter track each having at least an input interdigital transducer electrode and an output interdigital transducer electrode provided on said piezoelectric substrate,
• wherein the respective input interdigital transducer electrodes of said first and second filter tracks are connected in parallel;
• the respective output interdigital transducer electrodes of said first and second filter tracks are connected in parallel,
• overlapping widths of electrode fingers of said input interdigital transducer electrode and output interdigital transducer electrode are different from each other for each of said at least two filter tracks, and
• the first filter track differs from the second filter track in the number of peaks.
