DEV 1975 ARCHIMEDES L-Band Combining Fan-In Matrix, up to 16x16

DEV 1975 ARCHIMEDES L-Band Combining Fan-In Matrix, up to 16x16

The DEV 1975 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 1975 can combine up to eight inputs into each output, making it particularly suitable for satellite uplinks and other applications requiring flexible carrier aggregation.

Available in 16x8 and 16x16 base configurations, the matrix can also be supplied with fewer inputs or outputs and upgraded as requirements grow. Integrated RF sensing supports signal-level monitoring and automated switching arrangements for redundant signal paths.

The DEV 1975 operates across the extended 850-2450 MHz frequency range and supports 50 Ohm, 75 Ohm and optical input configurations. Variable input and output gain, optional slope control, redundant power supplies, a graphical local interface, SNMP and the DEV Web Interface provide flexible control in a compact 19-inch, 2 RU chassis.
