Guanella balun 1: 1 comparison between two and four conductors.

Used material: Amidon FT240-43 cores.

LEFT = 2 conductors RIGHT = 4 conductors

Left: transmission line with an impedance of 100 ohms.

Right: 2 transmission lines with an impedance of 100 ohms in parallel = 50 Ohms impedance.


Insertion loss / Return loss:

Return loss (SWR) 2 wires: Return loss (SWR) 4 wires:

Insertion loss 2 wires: Insertion loss 4 wires:

Common mode rejection:
