Abstract
A transformer balun for high rejection unbalanced lattice filters includes two symmetrical coils separated by a shielding element. In a further exemplary aspect, the transformer may include a conductor, which may be a third coil that operates with a capacitor to form a resonant circuit that enhances mutual coupling. Using either of the exemplary transformers provides improved performance in the passband while concurrently providing out-of-band rejection at levels exceeding seventy decibels (70 dB).
