DEV 2644 Ultra-Broadband 1:4 Splitter/4:1 Combiner, up to 2850 MHz

DEV 2644 Ultra-Broadband 1:4 Splitter/4:1 Combiner, up to 2850 MHz 

The DEV 2644 Ultra-Broadband Low-Loss Splitter/Combiner provides bidirectional passive RF signal distribution in a compact, wall-mountable enclosure. It can operate as either a 1:4 splitter or a 4:1 combiner, making it suitable for satellite, broadcast and broadband RF distribution systems.

Two versions are available. The DEV 2644/50 covers 500-2700 MHz with 50 Ohm SMA female connectors, while the DEV 2644/75 covers 400-2850 MHz with 75 Ohm precision F female connectors. DC signals are not blocked, allowing DC power or control signals to pass through the unit when required.
