Broadband DC Feeders

HYPERLABS offers high-performance, ultra-broadband DC Feeders with low insertion loss throughout the specified bandwidth range.

A DC Feeder functions like a Bias Tee, but without a DC blocking capacitor on the RF input. They allow for the insertion of a DC bias current or voltage onto the RF circuit path 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.
