This device contains a high-stability local oscillator, mixer and filters to convert an incoming frequency range of 1700-3500 MHz down to 0-1800 MHz. This can be used to extend the frequency range of VHF/UHF receivers, both WiNRADiO and third party products.
The local oscillator is stable enough for the downconverter to be usable even for narrow-band modulation modes, and has a low noise figure to be useful for professional as well as consumer applications.
For an alternative type of a high-performance downconverter, please see also our Antenna Multiplexer and Frequency Extender device.

Unlike most low-cost downconverters, the WiNRADiO WR-DNC-3500 downconverter features a high-stability 0.5ppm reference oscillator, to ensure excellent frequency stability at the output.
