HYPERLABS, a specialist in test and measurement technology, has released the broadest bandwidth DC Block in the industry. The HL8439. It is a ceramic-based product that has a bandwidth of 16 kHz to over 110 GHz, with a voltage rating of 10 V.
The HL8439 provides a typical insertion loss of less than 2 dB over the industry-best bandwidth and will remove DC bias from the input signal to prevent damage to various DC-sensitive devices or equipment. This makes it 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.

Furthermore, the HL8439 can also be used to improve RF power measurements when a power meter with DC sensitivities is used. The DC block operates over a temperature range from -40°C to +70°C and offers a phase stability of ±4° and an amplitude stability of ±0.1 dB over the operating temperature range., resulting in accurate performance, especially for RF test applications.
This RoHS/REACH-compliant DC block is available in a module that measures 1.41 x 0.377 x 0.377 inches with 1.0 mm connector (male/female) configurations on both the ends.
