Abstract: An apparatus includes an RF apparatus, and a wideband multi-band matching balun. The wideband multi-band matching balun includes a multi-band balun, which includes at least one three-element frequency-dependent resonator (TEFDR). The wideband multi-band matching balun further includes a differential-to-differential matching circuit coupled to the RF apparatus. The differential-to-differential matching circuit includes at least one TEFDR.
