This product was revised to fit a smaller housing in July 2022. Please refer to the datasheet for new dimensions.
The HL9434 is an ultra-broadband DC Block with a typical insertion loss of < 1 dB to 40 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.
