Abstract
In this dissertation, novel investigations are presented for modeling and
simulation of surface acoustic wave (SAW) devices. We hope that the
Presented results through this framework to be a strong seed for a SAW
production line in Egypt, in the near future.A minute notion for an accurate design of SAW delay lines, resonators
and their applications is presented. Fundamental and detailed studies for
the frequency response of SAW delay line built upon Quartz crystal at
70MHz synchronous frequency are investigated. A high performance
SAW delay line is constructed with minimum insertion loss using
different CAD tools.
A way for probing the propagation of Surface Acoustic Waves upon
piezoelectric substrate materials (e.g. lithium Niobate (LiNbO3) and
Gallium arsenide (GaAs) is performed.
3-D Finite element modeling was the best modeling technique choice to
perform the time domain (transient) analysis of SAW delay line at
different operating frequencies. The simulation results recorded using
COMSOL tool with nominal Hardware specifications of PC.
Different schematics for one and two-port of 433MHz SAW resonators
(SAWR) are built using equivalent circuit model (ECM). Scattering
parameters and insertion loss are predicted through frequency domain
simulation study using ADS tool.
IV
Different schematics for colpitts oscillators using SAWR are compared
with those of LC tank circuits in feedback circuit. AC sweep simulations
used to predict S-parameters of oscillators using ADS and Proteus. The
amplification stage of the oscillator design is performed using both
operational amplifier and BJT.
Development of one and two-port 433MHz SAWR resonators based
finite element modelling through COMSOL is investigated.
This dissertation contributes to use diversified simulation methods for
building and development sundry models for SAW delay lines and
resonators with their applications in the communications field. It also
contributes to use newfangled CAD tools for a fulfillment of the
simulation processes. Finally, it contributes to put imagine for reverse
extracting the equivalent circuit model parameters of SAWR from the
simulation results.
