HL8437 Broadband DC Block
The HL8437 is an ultra-broadband DC Block with a typical insertion loss of < 1.5 dB throughout the specified bandwidth range.
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.
