HL9437 DC Block (67 GHz)


Datasheet PDF

The HL9437 is an ultra-broadband DC Block with typical insertion loss of < 1 dB to 67 GHz. This device will remove DC bias from the input signaling to prevent damage to DC sensitive devices or equipment.

Other applications include optical communication systems, high-speed data systems, level shifting, cascading, and interfacing between devices with incompatible DC operating points. These devices 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.
