A SAW filter (using GUDTs for excitation and detection) has been described, requiring no external discrete components for the matching and the phase shifting networks. Using this design the filter can be fabricated on a single chip of substrate using the integrated-circuit fabrication procedures. The theoretical analysis has been done using the crossfield equivalent-circuit model of the filter and the results are in good correspondence with the experimental results.
