RFMD VCOs and Synthesizers Selection Page

Build the VCO or Synthesizer that meets YOUR needs

RFMD VCOs and Synthesizers offer a diverse set of frequency ranges, phase noise and packages to meet the diverse needs of our customers. The following provides both an overview of the product line as well as highlights of the various series. VCOs tend to be customer specific with multiple derivitives of an initial design. RFMD is exceedingly adept at creating VCOs and Synthesizers to meet customer requirements. Use the parametric search tool to find an oscillator that meets your needs.
