| Abstract: | A 2.5 ?-aperture SAW filter has been designed and tested. The single-mode nature of the waveguiding filter allows finger-length-weighting to be distributed between input and output transducers according to a simple procedure. The resulting filter has a stopband rejection in excess of 50 dB. |
