An apparatus, comprising:
- a radio-frequency (RF) apparatus;
- and
- a multi-band matching balun using passive components, the multi-band matching balun coupled to the RF apparatus, the multi-band matching balun including at least one three-element frequency-dependent resonator (TEFDR) and at most three reactive elements,
- wherein the at least one TEFDR provides functionality of an inductor having a frequency-dependent inductance or a capacitor having a capacitance having a frequency-dependent capacitance.
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 at least one three-element frequency-dependent resonator (TEFDR) and at most three lumped reactive elements (LREs),
- wherein neither the at least one three-element frequency-dependent resonator nor the at most three lumped reactive elements comprises variable or tunable capacitors or inductors, and
- wherein the at least one TEFDR provides functionality of an inductor having a frequency-dependent inductance or a capacitor having a capacitance 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 using passive components, the multi-band matching balun coupled to the RF apparatus to provide impedance matching and balun functionality, wherein the multi-band matching balun includes at least one three-element frequency-dependent resonator (TEFDR) and at most three reactive elements, wherein the at least one TEFDR provides functionality of an inductor having a frequency-dependent inductance or a capacitor having a capacitance having a frequency-dependent capacitance.
