Down Converters / Tuners

Utilizing Elcom’s advanced frequency architecture which incorporates a direct digital synthesizer (DDS) within a VCO based PLL synthesizer the tunable LO features low phase noise with fast tuning speed, low spurious and small tuning step size. The tuner-downconverter can be programmed remotely via the Ethernet interface or manually via the front panel keyboard with rotary knob.

Like all of our products, customers may realize little or no NRE costs through the application of our FlxGen© architecture to our family of down converters / tuners.

500 MHz to 26.5 GHz full band coverage is possible in a 1U nineteen inch rack. In house filter designers in conjunction with on site laser trimming allows for varying filter schemes based on the customer requirement.
