摘要： A dual mode, dual core power amplifier (PA) device includes a plurality of PA chains that generate output power according to an envelope tracking mode and a non-envelope tracking mode. The different modes can be selected to generate output power based on a set of predetermined criteria, which can be related to an input signal received by the system and related to a target power. A first PA chain with one or more PA cores is configured to operate in the envelope tracking mode based on at least a portion of the predetermined criteria being identified in the input signal and to generate output power with an envelope voltage supply that changes with an envelope of the input signal. In addition, a second PA chain with one or more PA cores can operate in a constant voltage supply mode or the non-envelope tracking mode according to the predetermined criteria.
