  Spectrum Microwave’s synthesizers offer wide bandwidth, multiple step size options, fast switching speedand low phase noise combined with the cost advantages of standardized packages. Frequency control options include Serial/parallel inputs, BCD/Binary format, or traditional thumbwheel switches.

  Spectrum also offers a several different options for locking to a specific source. The customer may choose internal reference crystal oscillators or low ppm OCXO’s. External reference frequencies can range from 10-100 MHz, depending on the customer’s system.

  These synthesizers feature rugged construction and the latest circuit techniques which makes them suitable for either military or commercial applications.

  Spectrum Microwave also designs and manufactures custom Direct Digital Synthesizer signal sources from 10 MHz to 14 GHz. Our designs use an embedded microcontroller which digitizes the analog control voltage (or reads the digital tuning word), then calculates and loads proper control words into the registers of the DDS.
