Abstract
Various embodiments relate to a reconfigurable integrated digital Chireix out-phasing power amplifier for use in high power base stations is described and a related method of said design. The power amplifier may include a power transistor circuitry having plurality of power transistors and shunt-series circuitry (L1C1, L2C2), a broadband combiner having Chireix compensation elements, and an impedance matching filter. The power transistor circuitry, the broadband combiner, and the impedance matching filter are integrated in a unified package. In one embodiment, the power amplifier is implemented in a real switch-mode to facilitate integration of the Chireix compensation elements so as to make the Chireix power amplifier tunable. A method of driving Chireix power amplifier structure is also described.
