Abstract :
This paper presents a ferrite and wire balun with performance similar to coaxial baluns. This balun makes two significant improvements over current technology: the wire impedance is adjusted for the ferrite and wire winding loading; and a trifilar wire is used to minimize skin effect losses. Insertion loss below 0.9 dB is achieved from 5 MHz to 2.5 GHz.
