LINEAR MODE AND NON-LINEAR MODE QUADRATURE PA CIRCUITRY |
摘要 |
Embodiments of the present disclosure relate to multi-mode multi-band radio frequency (RF) power amplifier (PA) circuitry, which includes a multi-mode multi-band quadrature RF PA coupled to multi-mode multi-band switching circuitry via a single output. The switching circuitry provides at least one non-linear mode output and multiple linear mode outputs. The non-linear mode output may be associated with at least one non-linear mode RF communications band and each linear mode output may be associated with a corresponding linear mode RF communications band. The outputs from the switching circuitry may be coupled to an antenna port via front-end aggregation circuitry. The quadrature nature of the quadrature PA path may provide tolerance for changes in antenna loading conditions.
