PEM QUARTZ CRYSTAL UNITS, FILTER LOW FREQUENCY 1 MC TO 10 MC. TYPES CR-(XM-49)/U THRU CR-(XM-52)/U.
Abstract
In the search for a solution to complex technical problems with the mass loading technique at frequencies 5 mc and 6 mc, three series of crystal designs were progressively introduced to uncover the role of other factors besides plateback in the suppression of unwanted modes. Although conventional crystal processing techniques were adequate to resolve problems at the 6 mc frequency, unconventional processing was required to achieve comparable progress at the 5 mc frequency. These fabricating techniques are described in the report. Parallel work effort, including the design and construction of plating masks and crystal mounts (for the high frequency vibration aspects of the PEM), is also described. (Author)
