Enhanced functionality with 10 MHz signal and DC voltage pass
A key feature of many of ETL components is the ability to pass or block a 10 MHz signal or DC voltage through the products, which can be used to power interconnecting components or pass a stable frequency reference to a LNB or BUC within the system.
ETL 4300 series offers passive 10 dB or 20 dB directional and proximity couplers for RF monitoring over L-band frequency range of 850 to 2150MHz. These devices are designed with a number of options for 10 MHz and DC pass block on the through line and/or coupled port with high current options available.
