HL934x Broadband DC Feeder
HL9345 Broadband DC Feeder (13 kHz to 50 GHz)
Datasheet PDF |Â S-parameters
The HL9345 is an ultra-broadband DC feeder with a typical insertion loss of 2.5 dB from 13 kHz to 50 GHz.
A DC feeder functions similarly to a bias tee, but without a DC blocking capacitor on the RF input.
The HL9345 allows for the insertion of a DC bias current or voltage onto the RF circuit path 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 PAM4 communications systems, optical communication systems, highspeed data systems, level shifting, and cascading.
This part is available as matched pairs or individual units with a variety of connector configurations.
