DEV 21x2 1:8 L-Band Splitters and Distribution Amplifiers, 800-2450 MHz

DEV 21x2/N 1:8 L-Band Splitters and Distribution Amplifiers, 800-2450 MHz 

The DEV 21x2/N Series includes 1:8 active L-band splitters and distribution amplifiers designed for satellite ground stations, teleports, broadcast facilities and professional RF distribution networks. Each model distributes one input to eight outputs across the 800-2450 MHz frequency range using 50 Ohm N female connectors.

Available models include the DEV 2132/N active splitter, DEV 2142/N managed distribution amplifier and DEV 2152/N redundant distribution amplifier. All models provide LNB power, RF sensing, a monitoring output and redundant power supplies in a compact 19-inch, 1 RU chassis. Managed models add variable gain, variable slope, SNMP control, the DEV Web Interface and optional signal recording.
