Oscillators, VCOs, Frequency Sources & Synthesizers
Manufacturers & Services

everything RFThese 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 test equipment that performs these functions, please click this link.
