WiNRADiO AMFE
|
The
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 3500MHz.
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 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 is specifically designed as an option for WiNRADiO
WR-G315 receivers.
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 AMFE-3500 is 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.
