ETL Systems MUXL1P-4103 L-Band & 10 MHz Multiplexer with DC Injection 850–2150 MHz

ETL Systems MUXL1P-4103 L-Band & 10 MHz Multiplexer with DC Injection 850–2150 MHz

The ETL Systems MUXL1P-4103 combines an L-band RF signal, an externally supplied 10 MHz reference, and external DC onto a common connection. It can also separate the RF and reference signals from the common connection for satellite communications and RF distribution applications.

The common port carries L-band RF, 10 MHz, and injected DC. The separate L-band port blocks DC and rejects 10 MHz, while the dedicated reference port passes 10 MHz and blocks L-band RF and DC.

The datasheet diagram identifies an 8–48 V external DC injection connection. The maximum DC voltage listed in the operating limits is 50 V; this is a limit rather than a generated supply output.

Mean L-band insertion loss is no more than 0.4 dB for the SMA, N-type, and listed BNC configurations, or 0.6 dB for F-type. The compact enclosure supports tapped screw and through-hole mounting for indoor installations.
