The GL Series was developed specifically to deliver repeatable
and reliable Ultra Broad Band performance up through 40 +
GHz. The GL Series of inductors provide Ultra-Low Insertion
loss, excellent return loss and extreme part to part performance
repeatability. The pyramid shape of the GL Series provides for
maximum inductance in the space available. The GL Series was
developed using a powdered iron core and gold plated
terminations that allow for easy use in hand solder applications.
The combination of Flat Frequency Response with the Ultra-Low
Insertion loss makes this an ideal component for optical data
systems, transimpedance amplifers and test equipment.
