Abstract

The problem of intermodulation distortions introduced by ferromagnetic materials inclusions in the construction of equipment used for transmission and processing of GSM signals is addressed. A Rayleigh model is implemented for determination of the response of ferromagnetic materials to two-tone signals. Results of experiments performed on coaxial transmission lines built with ferromagnetic materials and fed with two-tone signals are reported and compared to the predictions of the models.
