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.
