DEV 224x Managed L-Band Combining Amplifiers, 800-2450 MHz

DEV 224x Managed L-Band Combining Amplifiers, 800-2450 MHz  

The DEV 224x Series Managed L-Band Combining Amplifiers provide configurable 8:1, dual 8:1 or 16:1 active signal combining for satellite ground stations, teleports, broadcast facilities and professional L-band distribution networks. Available models include the DEV 2242, DEV 2243 and DEV 2245.

Operating across the extended 800-2450 MHz frequency range, these managed combiners provide variable gain, adjustable slope, RF sensing and dedicated monitoring outputs. DC-blocked inputs protect connected RF sources, while high input-to-input isolation minimizes interaction between signals.

Input and output ports can be configured independently for 50 Ohm, 75 Ohm or mixed-impedance operation using SMA, BNC or precision F female connectors. Ethernet connectivity enables remote monitoring and control through SNMP and the DEV Web Interface. Redundant AC power supplies and optional signal recording support mission-critical RF installations.
