Oscillators - Learn About Electronics
AMPLIFIERS 1 E. COATES 2007 -2013 Oscillators RF Sine Wave Oscillators RF Oscillators Radio Frequency Oscillators There are many different designs of sine wave Oscillators used in radio and communication equipment, usually using some form of resonant circuit to generate signals at radio frequencies from several tens of kHz to 1 GHz and above. A number of popular oscillator designs date back to the early 20th century when radio communication was being developed, and it has been the custom to name the various types of oscillator after their inventor. Any one particular design of oscillator can have several different forms, and each type of oscillator has certain advantages and disadvantages for any particular application.
coupling, such that less than half of the magnetic flux produce by one coil affects the other coil. Then k is assumed to have a value less than 0.5, and the inductors are said to be ‘loosely coupled’ or if the inductors share a common core with zero spacing between them, they are said to be ‘tightly coupled’ and k is assumed to have a value
