Abstract
The present disclosure relates to multi-mode RF power amplifier (PA) circuitry that may include a first PA path and a second PA path, each of which is fed from a common RF input. During a first operating mode, the first PA path receives and amplifies a first RF input signal via the common RF input, and during a second operating mode, the second PA path receives and amplifies a second RF input signal via the common RF input. To facilitate sharing of the common RF input, during the first operating mode, the second PA path is substantially de-coupled from the common RF input, and during the second operating mode, the first PA path is substantially de-coupled from the common RF input. By sharing the common RF input, size and costs of the multi-mode RF PA circuitry may be reduced.
