ETL Systems ODU-4100 IP67 L-Band & 10 MHz Multiplexer 850–2150 MHz

ETL Systems ODU-4100 IP67 L-Band & 10 MHz Multiplexer 850–2150 MHz

The ETL Systems ODU-4100 combines an 850–2150 MHz L-band RF signal and a 10 MHz reference onto a common connection, or separates them into dedicated RF and reference connections. Its compact IP67-rated enclosure supports outdoor satellite communications and RF signal distribution installations.

The common port carries both L-band and 10 MHz signals. Separate ports provide the L-band RF path and the 10 MHz reference path. The datasheet diagram shows DC blocking at all three ports.

Mean insertion loss is no more than 0.5 dB on the L-band path and 0.2 dB on the 10 MHz path. L-band flatness is ±0.1 dB, with 25 dB isolation. Available configurations provide 50Ω SMA or 50Ω N-type connectors.

The rugged enclosure supports through-hole mounting and operation from −40°C to +85°C.

This listing covers one ODU-4100 multiplexer in the selected connector configuration. Reference sources, RF equipment, cables, and mounting accessories are sold separately unless included in the quoted configuration. The unit routes an externally supplied 10 MHz signal; it does not generate a reference or provide DC power injection. Confirm connector selection and installation sealing requirements when requesting a quotation.
