Abstract: A mode-switching transformer selective on a band centered on a first frequency, comprising, between a same common mode input/output terminal and respectively one of two differential mode input/output terminals, a high-pass filter with a cut-off frequency smaller than said first frequency, a band-pass filter with a central frequency greater than said first frequency.
