Multifrequency rejection filter based on a SAW resonator
Abstract
Theoretical and experimental results are presented on the operation of a multifrequency rejection filter with a double-input SAW resonator which has appropriately chosen electrical coupling between the input and load. It is shown that it is possible to achieve deep rejection at several frequency points in such a filter. A rejection depth of about 50 dB was obtained experimentally.
