Available in PDF, EPUB and Kindle. Book excerpt: Accomplishments in instrumentation and oscillator design are reviewed with brief discussions. Of specific concern were methods of controlling temperature and voltage of oscillator units. Temperature control was accomplished by a large crystal oven, modified to hold several transistorized oscillator units. Temperature was meassured by a mercury thermometer calibrated to 0.01 C. Constant voltage for the oscillator units was supplied by transistorized regulated power supplies. Accurate voltage measurements were made with a sensitive dc microvoltmeter arranged to measure the voltage difference between the power supply and a reference battery. Of the 32 transistorized oscillator units constructed, 9 are described. Short-term frequency instabilities of less than 1 part in 10 to the 8th power were possible t frequencies from 100 to about 200 mc. Comparable stabilities at higher frequencies were possible through the use of frequency multipliers. Three tunnel-diode oscillator units, 4 rf amplifier units, 5 frequency multiplier units, and 1 combination amplifier-multiplier unit are described. (Author).

This book was released on 2012-12-06 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystal oscillators have been in use now for well over SO years-one of the first was built by W. G. Cady in 1921. Today, millions of them are made every year, covering a range of frequencies from a few Kilohertz to several hundred Mega hertz and a range of stabilities from a fraction of one percent to a few parts in ten to the thirteenth, with most of them, by far, still in the range of several tens of parts per million.Their major application has long been the stabilization of fre quencies in transmitters and receivers, and indeed, the utilization of the frequency spectrum would be in utter chaos, and the communication systems as we know them today unthinkable,'without crystal oscillators. With the need to accommodate ever increasing numbers of users in a limited spectrum space, this traditional application will continue to grow for the fore seeable future, and ever tighter tolerances will have to be met by an ever larger percentage of these devices.

Available in PDF, EPUB and Kindle. Book excerpt: The object of this handbook is to assemble a set of design methods for crystal oscillators in the frequency range of 1 KC to 200 MC with the aim of facilitating design, eliminating crystal unit misapplications, and reducing design costs. The handbook is not directed at the design of ultra-stable crystal oscillators, but rather at the non-temperature controlled, medium frequency stability oscillator commonly in use in many types of communications equipment. The handbook contains discussions of: (1) The electrical characteristics of crystal units, condition of usage, and methods of measurement. (2) Characteristics of tube and transistor amplifiers. (3) Characteristics of impedance transforming networks. (4) Detailed design information on series resonance and anti-resonance oscillators. (5) Design examples together with experimental evaluation data covering most of the 1 KC to 200 MC range. (Author).

Book excerpt: Oscillator circuits using quartz crystals as the frequency-controlling element are one the oldest basic RF circuits, dating aback the 1920s in vacuum tube designs. Today, they are more important that ever, but are now in IC form with the oscillator frequency "multiplied up" or "divided down" to synthesize a wide range of frequencies. Every RF/wireless device today controls its operating frequency with some form of a crystal oscillator circuit, and they also are the heart of clock functions used to control microprocessors and digital circuits. The book will introduce the basic concepts of crystal oscillator theory, describe their operation, and explore their various applications. Special attention will be given to environmental and operational parameters (such as keeping the crystal inside a temperature-controlled "oven" for increased frequency stability). In addition, there will be material on the use of crystal-controlled oscillators in embedded systems. *Introduces basic concepts of crystal oscillator theory. *Special attention given to environmental and operational parameters. *Includes guidelines for selecting the proper technology to accomplish the goal of the designer.
