ETL Systems MUXL1P-4100 L-Band & 10 MHz Multiplexer 850–2150 MHz

ETL Systems MUXL1P-4100 L-Band & 10 MHz Multiplexer 850–2150 MHz

The ETL Systems MUXL1P-4100 is an L-band multiplexer for satellite communications and RF signal distribution. It combines an 850–2150 MHz RF signal and a 10 MHz reference onto a common connection, or separates them into dedicated L-band and reference connections.

The common port carries both L-band and 10 MHz signals. The separate L-band port carries the RF signal, while the reference port passes 10 MHz. The datasheet diagram shows DC blocking at all three ports.

Mean L-band insertion loss is no more than 0.4 dB for the listed 50Ω versions or 0.5 dB for the 75Ω F-type version. Mean 10 MHz insertion loss is no more than 0.2 dB or 0.3 dB, respectively.

A rugged, compact enclosure supports tapped screw and through-hole mounting. Available configurations include 50Ω SMA, 50Ω N-type, 50Ω BNC, and 75Ω F-type connectors.

This listing covers one MUXL1P-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. RF performance depends on connector configuration. Confirm impedance, connector type, signal levels, and installation requirements when requesting a quotation.
