The WiNRADiO WR-G20DWC is a high-performance single-conversion frequency down-converter suitable for input frequencies up to 20 GHz.
This device contains a high-stability local oscillator, mixer and various filters to convert an incoming UHF to SHF frequency down to an intermediate frequency of 9 kHz to 2900 MHz, which is then directly applied to the receiver's antenna. This can be used to extend the frequency range of the WiNRADiO G39DDC and G527e receivers, as well as third-party products, into the high UHF and SHF regions.
Unlike most simple down-converters, the WR-G20DWC unit ensures excellent frequency stability by utilizing an ultra-high stability 0.01 ppm OCXO reference oscillator. This makes it usable even for narrow-band modulation modes, and due to its low noise figure it can also be used with high-end professional applications.
The WiNRADiO WR-G20DWC down-converter is especially suitable for use with the WiNRADiO G39DDC-series wideband receivers (WR-G39DDCe and WR-G39DDCi), whereby it integrates fully transparently to the user, i.e. the frequency entry and display of these receivers is automatically extended up to 20 GHz.
Physically, the WR-G20WDC unit can often stack neatly under (and sometimes above) the WiNRADiO receivers, thus providing a neat and elegant extension of their capabilities.
Third party receiver products can also be interfaced by using the supplied software application.
