HL9440M Broadband DC Bias Tee (Matched Pair)

This pair of amplitude- and phase-matched HL9440 Broadband DC Bias Tees is designed to minimize reflections of high-speed signals at the DC insertion point. DC bias tees allow for the insertion of a DC bias current into a circuit with minimal perturbation of the impedance of a 50 ohm transmission line.

NOTE: If you need a single, unmatched unit of the HL9440 DC Bias Tee, please see this page.
