Bias Tees & DC Blocks

Flexi RF offers a professional-grade selection of bias tees that seamlessly inject DC power into an RF circuit without compromising signal integrity. Our bias tee lineup covers an impressive frequency range, from as low as 30 KHz to an ultra-high 110 GHz, making them essential for biasing active components such as amplifiers, laser diodes, and optical modulators. Whether you require a standard SMA interface or precision 2.92mm, 2.4mm, 1.85mm, or 1.0mm connectors, each tee is engineered with low insertion loss and high isolation to keep your DC and RF paths strictly separated. Built with high voltage and current ratings (up to 1000 mA and 72 Volts), Flexi RF’s bias tees provide the rugged reliability and electrical stability needed for advanced lab testing and high-speed communication systems.
