2. Description

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 stacks neatly under or 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.
