A comprehensive manual of piezoelectric control of radio frequencies is offered. It is directed toward the design of oscillator circuits having opti¬mum operating conditions when employing Military Standard crystal units. Included is a survey of the development of the piezoelectric crystal art;descriptions and characteristics of all crystal elements and mounting methods that have found commercial application;a detailed study of the equivalent circuit characteristics of crystal units;analyses of basic piezo¬electric oscillator principles and of the effects of changes in various circuit parameters, using the Pierce oscillator as a reference circuit;analyses and recommended design procedures for all types of piezoelectric oscillator cir¬cuits used, or tested for use, in USAF equipments;schematic diagrams and tables giving actual circuit parameters of all available nonclassified piezoelectric oscillators now being used in USAF equipments;descriptions of all crystal units and crystal holders now being used in USAF equip¬ments, containing references and schematics of circuits employing those crystal units recommended for equipments of new design;a brief discus¬sion of crystal ovens and descriptions of ovens currently available for use with Military Standard crystal units;and a comprehensive index to increase the utility of the handbook as a reference manual. Circuit analyses, deriva¬tions of equations, and suggestions for design innovations whose sources are not directly acknowledged have originated with the author and so far as is known have not been specifically confirmed in practice.
