It adds a transmission-line transformer in cascade at the input, to convert an unbalanced signal to balanced at the input to the center-tapped transformer.
Amplitude balance, sometimes called "unbalance", is the absolute value of the difference in signal amplitude, in dB, between the two outputs of a center-tapped transformer using the center tap as a ground reference.
Phase balance, sometimes called "unbalance", is the absolute value of the difference in signal phase between the two outputs of a center-tapped transformer using the center tap as a ground reference, after subtracting the 180-degree nominal value of the phase-split.
To demonstrate the usefulness of this method for center-tapped transformers having a wide range of impedance ratios ([N.
Measurement of Amplitude and Phase Balance: Center-Tapped Transformers
A torroidal balun design utilizes a center-tapped transformer to extract the IF frequency, allowing it to have overlapping RF, LO and IF frequency ranges.
Like the ring mixer, it uses RF and LO center-tapped transformers.
