Original Abstract Submitted

an electronic device may include wireless circuitry with radios and a front end module coupled to an antenna. the module may include a multi-stage, multi-cell reconfigurable power amplifier and a radio-frequency coupler shared by the radios and different radio access technologies (rats). one or more processors may adjust a number of active stages of the power amplifier, circuitry and bias conditions of the active stages, tunable capacitors on the module, adjustable impedance matching networks on the module and/or in the power amplifier, and/or the coupler using a digital interface to place the module in different operating modes corresponding to different rats, power levels, modulation schemes, and/or frequencies. adjusting the operating mode may allow the power amplifier to be reconfigured to meet performance requirements while maximizing performance, meeting regulatory requirements, and minimizing power. sharing the power amplifier and the coupler across radios and rats may produce space and power savings.
