DEV 25xx Managed Bidirectional VSAT Distribution Systems, 800-2450 MHz

DEV 25xx Managed Bidirectional VSAT Distribution Systems, 800-2450 MHz  

The DEV 25xx Series Managed Bidirectional VSAT Distribution Systems combine an active receive splitter and an active transmit combiner in a compact 19-inch, 1 RU chassis. The DEV 2544 provides 1:4 Rx distribution and 4:1 Tx combining, while the DEV 2588 provides 1:8 Rx distribution and 8:1 Tx combining.

Operating across the extended 800-2450 MHz L-band frequency range, the DEV 25xx Series supports 50 Ohm, 75 Ohm and mixed-impedance configurations with SMA, BNC or precision F female connectors. Integrated LNB power, optional BUC power, variable gain, variable slope, RF sensing and 10 MHz reference options provide a flexible solution for professional VSAT and SATCOM networks.

Ethernet connectivity enables remote control and monitoring through SNMP and the DEV Web Interface. Optional signal recording, an internal 10 MHz reference and 24 or 48 VDC BUC powering further simplify bidirectional signal distribution between satellite modems and outdoor RF equipment.
