DEV 2232/N, 2242/N & 2252/N 8:1 L-Band Combiners

DEV 2232/N, 2242/N & 2252/N 8:1 L-Band Combiners

The DEV 22×2 Series provides active 8:1 L-band signal combining from 800 to 2450 MHz with 50 Ohm N female RF connectors. The DEV 2232/N, DEV 2242/N and DEV 2252/N combine eight input signals into one output within a compact 19-inch, 1 RU chassis.

All three models include DC-blocked inputs, RF sensing, an SMA monitoring port and redundant AC power supplies. The DEV 2232/N provides adjustable RF-sensing thresholds and front-panel alarm indication for straightforward local operation.

The managed DEV 2242/N and redundant DEV 2252/N add adjustable gain, variable slope, Ethernet, SNMP and the DEV Web Interface. The DEV 2252/N also incorporates a redundant amplifier to improve availability in mission-critical satellite and broadcast systems.
