Frequency Generation

US Technologies’ RF Microwave Group is involved in the design of frequency generation modules.  This expertise involves integrating various frequency source technologies into a module for a specific customer purpose.  Expertise involves designing phase lock loops, integrating fractional -N type topologies into a design, and using direct digital synthesis (DDS) technology.  Frequency ranges cover 30 MHz to 12 GHz.  Typical designs done in the past involve covering multiple octave frequency bands with multiple VCO’s that are used for electronic warfare applications in a pulsed application.  Such modules include the frequency tuning circuitry as well as amplitude pulse conditioning circuitry.  An example of an integrated broadband frequency source module is given below as an example.
