DEV 223x Active L-Band Combiners, 800-2450 MHz

DEV 223x Active L-Band Combiners, 800-2450 MHz 

The DEV 223x Series Active L-Band Combiners provide 8:1, dual 8:1 or 16:1 RF signal combining for satellite ground stations, teleports, broadcast facilities and professional L-band networks. Available models include the DEV 2232, DEV 2233 and DEV 2235.

Operating across the extended 800-2450 MHz frequency range, these active combiners support 50 Ohm, 75 Ohm and mixed-impedance configurations. SMA, BNC and precision F female connectors can be selected independently for each group of eight inputs and the associated output.

DC-blocked input ports protect connected RF sources, while integrated RF sensing provides an adjustable threshold and LED alarm indication. Dedicated monitoring outputs and redundant AC power supplies support reliable operation in a compact 19-inch, 1 RU chassis.
