WiNRADiO AMFE™ Antenna Multiplexer and Frequency Extender fulfills a
dual role of an antenna switching unit and a frequency down-converter,
making it possible to easily interface separate HF, VHF, UHF and SHF
antennas to a wide-band receiver, as well as provide frequency
down-conversion for input signals up to 8599 MHz.
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 96-1800 MHz, which is then directly applied to
the receiver's antenna. This can be used to extend the frequency range
of VHF/UHF receivers to high UHF and SHF regions, both for WiNRADiO and
third party products.
The local oscillator is stable enough for the down-converter to be
usable even for narrow-band modulation modes, and has a low noise figure
to be useful for high-end professional applications. |
The WiNRADiO AMFE™ Antenna Multiplexer and Frequency Extender is
especially suitable for use with WiNRADiO G315 series VHF/UHF receivers (WR-G315i
and WR-G315e), whereby it integrates fully transparently to
the user, i.e. the frequency entry and display of these receivers
automatically extend to 3500 or 8599 MHz (WR-AMFE-3500 or WR-AMFE-8600,
respectively), and the antenna switching is also automatic. Physically, the
WR-AMFE unit stacks neatly under or above a WR-G315e receiver, providing a
neat and elegant extension of its capabilities.
The 3500 MHz model (AMFE-3500) is specifically designed as an option for
WiNRADiO WR-G315 receivers, while the 8599 MHz model (AMFE-8600) can be also
used with other WiNRADiO receivers or any third party products (and
controlled using the supplied software application).
Unlike most simple down-converters, the WiNRADiO AMFE™ unit features a
high-stability 0.5 ppm reference oscillator, to ensure excellent frequency
stability at the output. An ultra-high stability reference oscillator
(0.01 ppm OCXO) is also available as an option.
 |
The AMFE™ unit interfaces neatly with the WiNRADiO WR-G315i
or WR-G315e receivers, where the software is able to
recognize the AMFE™ unit and expand the ranges of the frequency input
and display accordingly. Switching between the antennas and tuning the
local oscillator for the down-conversion is accomplished automatically.
The AMFE™ enclosure is also similar to that of the WR-G315e receiver and
stacks neatly on top or under it.
|
|
The 8600 MHz version (AMFE-8600) can be also used with any other
WiNRADiO or third party receiver to provide a cost effective antenna
switching and frequency conversion.
To take full advantage of the unit's capabilities, the receiver
should have a minimum frequency range of 96 to 1800 MHz, otherwise there
may be gaps in the frequency coverage of the SHF input (the antenna
switching of the HF, VHF and UHF inputs does not apply any frequency
conversion).

The AMFE-3500 and AMFE-8600 are computer controlled by the
G315 USB interface which automatically multiplexes the four antenna inputs for
HF,
VHF and UHF into the one G315 antenna input. The actual received frequency
will be displayed.
For the G305 and any other receiver, a stand-alone
application program (http://www.winradio.com/home/amfe-software.htm)
can be used for control
of the AMFE-8600, but it will not display the received frequency; this is shown,
however, along with the intermediate frequency to which the receiver should
be tuned, by the AMFE-8600 software. There is no such software available for the
AMFE-3500.
