DEV 1976 ARCHIMEDES L-Band Combining Fan-In Matrix, up to 64x44

DEV 1976 ARCHIMEDES L-Band Combining Fan-In Matrix, up to 64x44 

The DEV 1976 ARCHIMEDES L-Band Combining Fan-In Matrix routes and combines multiple input signals into selected output channels. Unlike a conventional fan-out distribution matrix, the DEV 1976 can combine up to eight inputs into each output, making it particularly suitable for satellite uplinks, carrier aggregation and redundant transmission systems.

Available in standard 32x22, 32x44, 64x22 and 64x44 configurations, the 4 RU matrix can also be supplied with fewer channels and field-upgraded as requirements grow. Integrated RF sensing supports signal-level monitoring and automatic switching arrangements that maintain service if an assigned signal path fails.

The DEV 1976 operates from 850 to 2450 MHz and supports 50 Ohm, 75 Ohm and optical input configurations. Available options include variable slope, LNB power, an integrated spectrum analyzer, an integrated TV receiver, a multi-touch display and controller redundancy. Remote control and monitoring are provided through SNMP and the DEV Web Interface.
