Abstract : Due to the new etching technology, the Argon Ion beam technique, CEPE is now able to provide piezoelectric devices with an enlarged useful bandwidth by the use of resonators operating either in the fundamental mode or in a low overtone mode (i.e. 600 MHz 3rd overtone). The results issued from several applications, already used in new-generation Telecommunication systems, exhibit behaviour similar to that observed at lower frequencies (i.e. 30 MHz to 50 MHz) with conventional resonator lapping technologies.
