Synthesizers
           
 

We are experienced in developing RF and microwave synthesizers and signal source for communications applications. Shown here is a sample of our capabilities. To see our board level synthesizers click here.

  6GHz multiple output synthesizer. Four highly isolated +10dBm outputs. One of 16 predetermined frequencies can be selected from 5 to 7 GHz. Includes multiple 10MHz reference outputs and/or external reference input.

      2.0-2.5GHz high spectral purity and fast switching synthesizer for a fast frequency hopping digital data radio. This synthesizer module uses and extremely pure integer-N synthesizer combined with a DDS synthesizer in order to produce fast switched frequencies over a broad range in small step sizes.
 
        100MHz precision frequency reference with programmable phase outputs.
 
We have developed a number of software tools to help design PLLs. This MathCad file was developed by Stuart Rumley to help select the filter components for passive second order and third order PLLs. You can download either htm or mcd .
