Couplers

ETL Systems’ RF Couplers are compact, cost-effective components crucial for RF monitoring. A key feature of many ETL components, including these couplers, is the ability to pass or block a 10 MHz signal or DC voltage. This functionality allows for powering interconnecting components or providing a stable frequency reference to LNBs or BUCs within a system. The ETL 4300 series provides passive 10 dB or 20 dB directional and proximity couplers, available in both indoor and outdoor housing. These couplers are designed for RF monitoring across IF and L-band frequency ranges, specifically from 50 to 2450MHz. They offer numerous options for 10MHz and DC pass/block on the through line and/or coupled port, with high current options also available. The couplers operate across IF, L, and extended L-band frequencies, providing enhanced functionality with 10MHz signal and DC voltage pass capabilities.
