Amidon toroid for broadband and EMI filters

Suitable for HF high power balun up to 2 KW, it is particulary suggested for HF band

Example application of a 1:1 Balun 1:1 on HF band

Frequency
(MHz)
Impedance
(Ohm)

1m RG400 or RG142 (6+6 turns)
the second turn is reversed
(tested with HP 4191A impedance analyzer)

1.5 2000
3.0 6000
10 2500
20 1100
28 800

Note: we remind that for the proper operation of a 1: 1 Balun it is required an impedance of at least 500 Ohms (preferably 1000), this gives the possibility to obtain a good symmetrization of the coaxial cable on a balanced load
