ETL Systems MUXL1P-4104 L-Band & 10 MHz Multiplexer with DC Injection 850–2150 MHz

ETL Systems MUXL1P-4104 L-Band & 10 MHz Multiplexer with DC Injection 850–2150 MHz

The ETL Systems MUXL1P-4104 combines or separates L-band RF and an externally supplied 10 MHz reference, with a separate connection for external DC injection. It supports indoor satellite communications and RF distribution systems operating from 850–2150 MHz.

The datasheet diagram shows an 8–24 V DC connection feeding one RF port. Both opposite signal ports are DC blocked. The opposite RF port is marked for RF and 10 MHz pass, while the dedicated reference port passes 10 MHz.

Mean insertion loss is no more than 0.4 dB on both the L-band and 10 MHz paths. The unit provides 20 dB isolation and uses 50Ω N-type RF connectors.

The rugged, compact enclosure supports tapped screw and through-hole mounting for integration into RF systems.

This listing covers one MUXL1P-4104-N5N5N5 multiplexer. External DC supplies, reference sources, RF equipment, cables, and mounting accessories are sold separately unless included in the quoted configuration. The unit does not generate DC power or a 10 MHz reference. The datasheet marks 10 MHz pass at the opposite RF port; confirm the required signal routing, DC current capacity, polarity, and connection details when requesting a quotation.
