The HL9647 from Hyperlabs is a Bias Tee that operates from 125 kHz to 67 GHz. It can handle a maximum DC bias current of 1000 mA and has a breakdown voltage of ±30 V. The bias tee has an insertion loss of less than 2.3 dB, an amplitude match of ±0.1 dB, and a phase match of ±4° at 40 GHz. It is available in a RoHS compliant package that measures 49.53 x 33.02 x 13.46 mm with 1.85 mm plug-plug, plug-jack, and jack-jack connectors. The HL9647 is ideal for biasing amplifiers, lasers, optical modulators, and other optical communication systems, high-speed data systems, cascading, interfacing between devices with incompatible DC operating points, and level shifting applications.
