The Advantech Wireless ARWF-LX is a rack mounted 950 – 2150 MHz RX Wide Band Front End Frequency Down Converter that accepts an input in super extended L-Band and provides an output in a fixed L-Band (1100 MHz). The new unit can be used for SCPC, DAMA and TDMA as well as full transponder HDTV and traditional analog TV. Spectral purity, stability, and group delay characteristics fully meet or exceed the requirements of all domestic, international, and regional commercial satellite networks.
Cristi Damian, VP Business Development at Advantech Wireless said that this innovative Satellite Down Converter is designed to overcome a potential shortcoming in existing teleports to allow them to accommodate newer satellites’ (including HTS) Wide Receive Band. The RX band covered by these new and powerful satellites is too large to be handled by the legacy demodulators which typically have a maximum range of 950-1700 MHz.
Mr. Damian continued that most of the already deployed SCPC or TDMA networks are not able to access the full wide band satellite RX band, which can be up to 2.5 GHz wide putting severe limitations on bandwidth access, and on traffic increase. Today they need expensive additional demodulators to cover the frequency gaps at the Hub, but there is no solution for the remote terminals. This new wide band down converter can receive any carrier within 950-2150 MHz and down convert it to 1100 MHz, which can be received by legacy demodulators. It will allow service continuity in existing networks, and access to more bandwidth with minimal upgrade cost.
