VHF QUARTZ CRYSTAL UNITS CR-(XM-38)/U 150 MC TO 200 MC
Abstract
The purpose of this effort is to develop techniques necessary to fabricate and evaluate 9th overtone units from 150 mc to 200. The problems are: (1) meeting the maximum series resistance specification of 80 ohms after adjustment to frequency; (2) correlation of final frequency adjustment to the actual frequency as measured in the TSM-15; and (3) optimizing yields sufficient to adhere to the requirement of 'minimum shrinkage.' Data on 150- and 174-mc 9th overtone units, employing different electrode sizes is given. First efforts to adjust to frequency by etching the aluminum electrodes are reported. Data is given on holder resistance and inductance.
