HL8445 Broadband Bias Tee w/ Sense Port (50 kHz to 50 GHz, 175 mA)
$1,345.00 – $2,695.00
The HL8445 is an ultra-broadband bias tee including a sense port, with a maximum insertion loss of 1.75 dB from 35 kHz to 50 GHz.
These devices block any existing DC signal and allows for the insertion of a DC bias current into a circuit with minimal perturbation of the impedance of a 50 ohm transmission line.
These devices can be used for biasing amplifiers, lasers, optical modulators, and other devices.
Applications include 112 Gbps PAM4 communications systems, optical communication systems, high-speed data systems, level shifting, cascading, and interfacing between devices with incompatible DC operating points.
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.
