HL9444 Broadband Bias Tee
The HL9444 is an ultra-broadband bias tee with a maximum insertion loss of 1.55 dB from 35 kHz to 40 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.
