Oscillators, VCOs, Frequency Sources & Synthesizers
Manufacturers & Services
companies manufacture oscillators, frequency sources, and frequency synthesizers. Oscillators come in many varieties
with many different frequency determining devices. Everything from low-tech LC (inductor-capacitor) tank circuits
to crystals and YIG type oscillators are used. High and low accuracy and stability, frequency ranges, fixed frequency
and variable frequency, are among the available options. If you are looking for
