Claims20
An apparatus, comprising:
- a radio-frequency (RF) apparatus;
- and
- a multi-band matching balun coupled to the RF apparatus, the multi-band matching balun including a plurality of capacitors and a plurality of inductors used to realize either an inductor having a frequency-dependent inductance or a capacitor having a frequency-dependent capacitance,
- wherein none of the plurality of capacitors and none of the plurality of inductors is variable or tunable.
An apparatus, comprising:
- a radio-frequency (RF) apparatus;
- and
- a multi-band matching balun coupled to the RF apparatus, the multi-band matching balun comprising a three-element frequency-dependent resonator, wherein the three-element frequency-dependent resonator realizes either an inductor having a frequency-dependent inductance or a capacitor having a frequency-dependent capacitance.
A method of operating an apparatus that includes a radio-frequency (RF) apparatus, the method comprising using a multi-band matching balun coupled to the RF apparatus to provide impedance matching and balun functionality, wherein the multi-band matching balun includes a plurality of capacitors and a plurality of inductors used to realize either an inductor having a frequency-dependent inductance or a capacitor having a frequency-dependent capacitance, and none of the plurality of capacitors and none of the plurality of inductors is variable or tunable.
