Resonance active balun

A resonance active balun reduces unbalance between differential signals by performing the switching operation of the differential signal generated by a resonant unit. A resonant unit(100) converts the single ended signal through the input terminal into the differential signal. A differential switch part(200) is formed with the cross-linking structure between the differential signal terminal of the resonant unit and the first and second signal output terminals. The differential switch part outputs the differential signal through the first and second output terminals by amplifying the differential signal from the resonant unit and reducing the unbalance at the same time.
