ETL Systems Dextra 22481 8-Way IF Active Splitter and Combiner

ETL Systems Dextra 22481 8-Way IF Active Splitter and Combiner

The ETL Systems Dextra 22481 is an 8-way IF distribution unit configurable for signal splitting or combining. It offers 20–200 MHz and 50–1000 MHz frequency configurations in a 1U chassis, with a −20 dB monitor port, Ethernet monitoring, and dual redundant power supplies. Splitter operation also supports switchable LNB power.

Key Features

• Configurable for 8-way splitting or 8-way combining

• Front-panel port for signal monitoring

• Optional redundant amplifiers (OPT-R), DC pass from port 1 to the common port (OPT-D), or both (OPT-RD)

• Remote monitoring of power supplies and, in splitter mode, LNB power and current

Confirm the frequency configuration when ordering. The datasheet’s front-page frequency callout differs from its RF specification table; the ranges above follow the table.
