Passive directional and proximity couplers for RF monitoring

RF Couplers

Compact, cost-effective RF coupler components

A key feature of many of ETL’s 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’s 4300 series offers passive 10 dB or 20 dB directional and proximity couplers in both indoor and outdoor housing for RF monitoring over IF and L-band frequency ranges of 50 to 2450MHz. These devices are designed with numerous options for 10MHz and DC pass block on the through line and/or coupled port with high current options available.
