TUNABLE TRANSFORMER
Techniques are disclosed implementing a tunable transformer (L1-L3) with additional taps in at least one of the three coils (102, 104, 106). The tunable transformer enables the resonant frequency within RF transceiver matching networks to be adjusted without substantially impacting the output power...

| description | Techniques are disclosed implementing a tunable transformer (L1-L3) with additional taps in at least one of the three coils (102, 104, 106). The tunable transformer enables the resonant frequency within RF transceiver matching networks to be adjusted without substantially impacting the output power at resonance. The tunability of the transformer is partially driven by the insertion of additional coils (106) within the transformer, which are selectively switched and may be further coupled with a tunable capacitance (108). The tunability of the transformer is further driven via the use of at least one multi-tap transformer coil (104), which allows electronic components to be coupled to different coil taps to thereby facilitate an adjustable DC inductance. Doing so counteracts changes in mutual inductance between the non-switched coils, and facilitates the stabilization of output power with shifts in resonant frequency. |
