Oscillators are a fundamental building block of almost every electronic system, analogue or digital. Oscillators provide the signal source for all microwave systems, including both transmitters and receivers.
The conditions for oscillation are simple, the loop gain of a network has to be unity or more, and the total phase shift through the feedback loop must be an integer of 360 degrees. This type of feedback is known as positive, or regenerative feedback. In practice the feedback network usually has a resonance, which determines the output frequency.
A huge variety of materials may be used as the base of an Oscillator, each with distinct properties and performance benefits for specific frequencies or signal quality.
Accutronics offers a wide variety of Oscillator products for all RF and Microwave systems, for any required frequency (or frequency range) and for general purpose use to extremely high performance units for ultra-stable system requirements.
