The HL9538 is an ultra-broadband DC blocking adapter between series (1.0 mm to 1.85 mm) with a typical insertion loss of < 2 dB throughout the specified bandwidth range.

Incorporating both the DC block and the series adapter into a single device removes interfaces which improves overall system performance.

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.

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