ETL Systems MUXL1P-4111 L-Band & 10 MHz Multiplexer with DC Injection 850–2150 MHz

ETL Systems MUXL1P-4111 L-Band & 10 MHz Multiplexer with DC Injection 850–2150 MHz

The ETL Systems MUXL1P-4111 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 indoor satellite communications and RF distribution systems.

The common port carries L-band RF, 10 MHz, and injected DC. The separate L-band and 10 MHz reference ports are DC blocked. A separate DC injection connection accepts an external 8–24 V supply, as shown in the datasheet diagram.

Mean L-band insertion loss is no more than 0.4 dB for the 50Ω versions or 0.6 dB for the 75Ω versions. Mean 10 MHz insertion loss is no more than 0.2 dB and 0.4 dB, respectively. Isolation is 22 dB typ. for 50Ω configurations and 18 dB typ. for 75Ω configurations.

The rugged, compact enclosure supports tapped screw and through-hole mounting. Five connector configurations provide options for 50Ω and 75Ω RF systems.
