| titleOfInvention | SURFACE ACOUSTIC WAVE RESONATOR |
| abstract | THE INVENTION CONCERNS SURFACE ACOUSTIC WAVE DEVICES. A SURFACE ACOUSTIC WAVES RESONATOR INCLUDES IN PARTICULAR A PIEZOELECTRIC SUBSTRATE 11 WHICH CARRIES A TRANSDUCER 14 WITH PROHIBITED ELECTRODES WITH A METAL-FACE STRUCTURE, AND TWO REFLECTORS 12, 13 CONSTITUTED BY A LARGE NUMBER OF ELECTRODES BY SEPARATE SIDEDS. A PARTICULAR RANGE IS CHOSEN FOR THE RATIO BETWEEN THE PERIOD OF THE REFLECTOR ELECTRODES, IN ORDER TO OPTIMIZE THE PERFORMANCE OF THE RESONATOR BY MAKING THE CENTRAL FREQUENCY OF THE TRANSDUCER AND THAT OF THE REFLECTORS COINCIDE. APPLICATION TO MINIATURE FILTERS IN METRIC AND DECIMETRIC BANDS. |
