Claim 14:
15. A method of operating an apparatus that includes a radio-frequency (RF) apparatus, the method comprising using a wideband multi-band matching balun using passive components to provide simultaneous balun and impedance matching functionality in multiple bands, wherein the wideband multi-band matching balun includes a multi-band balun coupled to a differential-to-differential matching circuit, wherein the multi-band balun comprises at least one three-element frequency-dependent resonator (TEFDR), and wherein the differential-to-differential matching circuit comprises at least one TEFDR, wherein the at least one TEFDR in the multi-band balun, the differential-to-differential matching circuit, or both, provides functionality of an inductor having a frequency-dependent inductance or a capacitor having a capacitance having a frequency-dependent capacitance.
