ETL Systems Bias Tee / DC Injectors

ETL’s Bias Tees operate across a range of frequencies and are available with 50Ω or 75Ω impedance and various connector types. Each module is designed for easy mounting on a base or panel and is housed in non-hermetic EMC-shielded enclosures. Options include a 10MHz rejection filter and a high-current version for powering multiple modules or devices up to 5A and 48V.

Our Bias Tees enable DC bias to be added or removed from an RF line without disrupting the RF signal, providing a combined path for DC power and RF signals—ideal for powering amplifiers and frequency converters in transmission systems.

Typical fields of application include:

• Microwave Links
• Telecom Infrastructure
• Satellite Systems
• Test & Instrumentation
