Design, Development and Evaluation of a Doubly Rotated AK-Cut Quartz Crystal

Abstract

This report describes the work accomplished in designing, developing and evaluating a doubly rotated AK-cut quartz crystal. Standard production processes were used to fabricate AK-cut crystals with 0 = 36.48oo = 26.000 or 0 = 35.000 and 0 = 25.000. Frequency versus temperature characteristics room temperature mode spectra and 'G' sensitivity data were the main sources of data for evaluation. Crystals were fabricated at low frequencies and through subsequent lapping and polishing operations the frequencies were increased to determine a range of useful frequencies. Comparisons made of 'B' mode to 'C' mode coupling and separation. Unwanted mode suppression, angular rotation tolerances and 'G' sensitivity. AK-cut lateral field resonators (AK-LFR) were also evaluated.
