Oscillators, VCOs, Frequency Sources & Synthesizers
Manufacturers & Services

These 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.

Please consider contacting my advertisers first.

My policy is to only list companies that actually manufacture product or offer services related to the page title subject. Product distributors and sales representatives are not listed (they have their own page). This helps guarantee that each listing offers a unique product or service. NOTICE: I am no longer adding hyperlinks. Your best bet is to use a search engine to find company websites directly.
