HL9349 Broadband DC Feeder

The HL9349 is an ultra-broadband DC feeder with a typical insertion loss of 2.5 dB from 13 kHz to 110 GHz.

A DC feeder functions similarly to a bias tee, but without a DC blocking capacitor on the RF input.

The HL9349 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.
