ETL Systems MUXL1P-4112 L-Band & 10 MHz Multiplexer with DC Injection 850–2150 MHz

ETL Systems MUXL1P-4112 L-Band & 10 MHz Multiplexer with DC Injection 850–2150 MHz

The ETL Systems MUXL1P-4112 combines an L-band RF signal and an externally supplied 10 MHz reference onto a common connection, or separates them into dedicated signal paths. A separate DC injection connection supports an external DC feed for indoor satellite communications and RF distribution systems.

The common port carries L-band RF, 10 MHz, and DC. The separate L-band port passes RF and DC while rejecting 10 MHz. The dedicated 10 MHz reference port is DC blocked.

Mean insertion loss is no more than 0.4 dB on both the L-band and 10 MHz paths. L-band flatness is ±0.15 dB, with 20 dB isolation. Available configurations provide 50Ω SMA or 50Ω N-type connectors.

The compact enclosure supports tapped screw and through-hole mounting. Maximum RF input power is +21 dBm (125 mW), and the datasheet lists a maximum DC voltage of 50 V on any RF port.

This listing covers one MUXL1P-4112 multiplexer in the selected connector configuration. 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 50 V specification is a maximum operating limit; confirm the permitted DC injection range, current capacity, polarity, and connection details when requesting a quotation. RF input must remain within +21 dBm (125 mW).
