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.

The WiNRADiO WR-DNC-3500 Frequency Downconverter is especially suitable for use with WiNRADiO
G3 series VHF/UHF receivers, such as the WR-G305i, WR-G305e,
WR-G315i and WR-G315e receivers.
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.
Installation
|
The downconverter is connected to the antenna and the receiver via an SMA connector and a suitable low-loss coaxial cable. In this type of installation the power
is applied directly to the downconverter. We recommend using well-filtered power, preferrably that of a linear power supply, such
as WiNRADiO SF-41 series (which is already supplied with the downconnverter).
|
|
Alternatively, the downconverter can be placed closer to the antenna and powered via the coaxial cable. On the receiver side, the power can be injected
via WiNRADiO WR-BT-3500 "Bias T" device. This would be a preferred option to minimize losses in the cable if the antenna is located at a greater distance from the receiver.
