| Abstract: | his peper presents the SAW filters for home made BP machine, which feature broad band and low insertion loss. In order to decrease the loss,a three-transducer structure with SPUDT was used,and good results were obtained.The frequency response curves of the SAW fil-ters are given at last. |
