An accurate solution to the coupled electromagnetic and acoustic fields set up by an interdigital
transducer on the surface of a piezoelectric substrate is obtained. Full account is taken of …

Small sized, highly selective solidly mounted bulk acoustic wave (BAW) band pass filters
are of great interest for mobile and wireless systems operating in the frequency range of 0.8 …

The paper shows how the variational principle can be used to analyse the generation of
ultrasonic surface waves by an infinite interdigital array of electrodes on the surface of a …

A reference oscillator operating at 2 GHz and based on a temperature compensated bulk
acoustic wave resonator is presented. Temperature compensation is realized by addition of an …

… The emphasis is on modeling silicon IC’s and MCM’s for RF applications such as mobile
communications [3], [4], although the general method is widely applicable. The modules of …

One of the most common materials and orientations used for SAW bandpass filters is YZ
LiNbOg. The principal attractions of this cut apart from its low cost are 1) a high piezoelectric …

Bulk-wave composite resonators (BWCRs) employing thin piezo-electric films on silicon
membranes have received considerable attention because of potential for integrated selectivity …

The Boltzmann equation is modified to examine the effects of a range of scattering mechanisms
on the DC conductivity of semiconductor material in the form of thin sheets and fine wires…

A more accurate representation of an interdigital array is obtained by using an equivalent
circuit intermediate between the crossed-field and in-line-field models, with negative …

Bulk acoustic wave (BAW) filters are competing successfully in the range of 800 MHz to 10
GHz with SAW filters. USPCS and UMTS filters require a bandwidth of 60 MHz at …
