Microelectronics component designing by Cadence software

Abstract

Acoustic-electronic radio components on surface acoustic waves (SAW) are the most promising class of radio-frequency filters in the frequency range from 20 to 2500 MHz. The most important feature that determines the rapid introduction of acoustoelectronic radio components into modern information systems is the possibility of combining manufacturing processes with micro and nanotechnologies, high temperature stability and reliability, and small weight and size characteristics. Element performing excitation and reception of acoustic waves in all devices types is an interdigital transducer (IDT), which is a grid of metal electrodes deposited on the surface of the piezoelectric.
