The WiNRADiO AMFE™ Antenna Multiplexer and Frequency Extender fulfills a dual role of an antenna switching unit and a frequency downconverter, making it possible to easily interface separate HF, VHF, UHF and SHF antennas to a wide-band receiver, as well as provide frequency downconversion 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 downconverter 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 downconverters, 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 downconversion is accomplished automatically. The AMFE™ enclosure is also similar to that of the WR-G315e receiver and stacks neatly on top or under it.
