DEV 2194 2x1:8 or 1:16 L-Band Distribution Amplifier, 700-2300 MHz

DEV 2194/75 2x1:8 or 1:16 L-Band Distribution Amplifier, 700-2300 MHz 

The DEV 2194/75 L-Band Distribution Amplifier provides selectable dual 1:8 or single 1:16 RF signal distribution across the 700-2300 MHz frequency range. An integrated 1:2 splitter allows the unit to operate as two independent 1:8 distribution amplifiers or as one cascaded 1:16 distribution amplifier.

Designed for satellite ground stations, teleports, broadcast facilities and professional SATCOM networks, the DEV 2194/75 features 75 Ohm F female inputs and 75 Ohm BNC female outputs. Adjustable gain, variable slope, LNB power, RF sensing and remote management provide flexible control and dependable L-band signal distribution in a compact 19-inch, 1 RU chassis.
