HL8438 Broadband DC Block
The HL8438 is an ultra-broadband DC Block with a typical insertion loss of < 2 dB over a bandwidth of 16 kHz to 95 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 224 Gbps PAM4 communications systems, optical communication systems, high-speed data systems, level shifting, cascading, and interfacing between devices with incompatible DC operating points.
