QUARTZ CRYSTAL UNIT CR-(XM-37)/U
Abstract
The CR-(XM-37)/U quartz crystal unit is a metal plated unit designed to operate at series resonance on the 7th mechanical overtone in the range of 150 to 200 mc. Holder type is the HC-18/U. Manufacturing this unit without resorting to screening and with a minimum of shrinkage points up the following problems (1) angular control through sawing process, (2) lapping and final polish, (3) methods of handling thin blanks, (4) frequency control for minimum finishing, (5) cleaning and base plating, (6) mounting thin blanks in holders, (7) cementing, and (8) correlation of final frequency test equipment with AN/TSM-15. Requirements satisfying these problems are listed. (Author)
