Advantech Wireless ARWF-LX 1100 MHz Single Channel RF Downconverter
The Advantech Wireless ARWF-LX is a single-channel L-band RF downconverter designed to convert RF signals in the 950 to 2150 MHz frequency range to a fixed 1100 MHz IF output. It provides a practical solution for satellite communication, RF signal processing, and other professional systems that require controlled L-band frequency conversion.
The converter features a 50 Ω RF input with a Type N female connector and 16 dB return loss. Its 1100 MHz IF output provides up to +5 dBm output power at P1dB, while the standard 50 Ω output impedance supports integration with compatible RF and IF equipment.
The ARWF-LX provides a minimum 30 dB conversion gain at the maximum gain setting and a 40 dB gain adjustment range from -10.0 dB to +30.0 dB. Gain can be adjusted in 0.1 dB steps, allowing operators to configure signal levels according to different RF system requirements.
Its gain flatness, gain stability, in-band spurious performance, and phase noise characteristics make the converter suitable for satellite ground stations, RF distribution systems, signal processing equipment, and telecommunications infrastructure. External and internal reference options also support frequency stability for professional RF applications.
The 1U rack-mount design fits standard 19-inch equipment racks, while Ethernet, RS-232, and RS-485 interfaces provide monitoring and control capabilities. The unit also provides LNB 10 MHz reference and DC supply functions over the L-band input, making it suitable for integrated satellite RF systems requiring centralized signal and LNB management.
