Design and Performance of Coplanar Waveguide Bandpass Filters

July 1, 1983
Author(s)
Dylan F. Williams, S E. Schwarz
End-coupled resonator bandpass filters built in coplanar waveguide are investigated. The admittance inverter parameters of the coupling gaps between resonant sections are deduced from experiment, and bandpass filter design rules are developed. This allows

Temperature variation of SAW power flow angle

February 19, 1981
Author(s)
Dylan F. Williams, F Y. Cho
The power flow angle of surface acoustic waves in quartz not on a crystalline axis of symmetry is shown to vary rapidly with temperature. Experimental results and theoretical calculations are presented demonstrating the dependence of the acoustic power

Numerical Analysis of Doubly Rotated Cut SAW Devices

April 30, 1980
Author(s)
Dylan Williams, F Y. Cho
Results of a numerical study of the properties of surface acoustic waves (SAW) on doubly rotated cuts of alpha quartz are presented. First and second order TCF's have been calculated on a 10° x 10° x 10° grid spanning the range of angles (XY wlt) 0 to 3O°/
