Broadband Bias Tees

HYPERLABS offers a variety of ultra-broadband bias tees with low insertion loss throughout the specified bandwidth range.

All of these bias tees block any existing DC signal and allows for the insertion of a DC bias current into a  circuit with minimal perturbation of the impedance of a 50 ohm transmission line.

These devices can be used for biasing amplifiers, lasers, optical modulators, and other devices. Applications include 112 Gbps PAM4 communications systems, optical communication systems, high-speed data systems, level shifting, cascading, and interfacing between devices with  incompatible DC operating points.

When ordered in pairs, these components can be matched for use with HYPERLABS and other components, preserving the matching of the rest of the system.

For applications requiring a sense port to accurately measure DC voltage, please see our line of Kelvin Bias Tees.
