Datasheet PDF S-parameters

The HL9439 is an ultra-broadband DC Block with a typical insertion loss of < 2 dB to 85 GHz.

The DC block will remove DC bias from the input signal to prevent damage to DC-sensitive devices or equipment.

These devices are suitable for use in 112 Gbps PAM4 communications systems, optical communication systems, high-speed data systems, level shifting, cascading, and interfacing between devices with incompatible DC operating points.

They can also be used to improve RF power measurements when a power meter with DC sensitivities is used.

This part is available as matched pairs or individual units with breakdown voltage of 11 V or 30 V and a variety of connector configurations.
