Abstract
Systems and methods for driving using a radio-frequency integrated circuit to drive one or more front end modules. The front end modules provide signal flexibility to an electronic device. The radio-frequency integrated circuit drives the one or more front end modules via dual-pole, dual-throw switches that enable a pair of radio-frequency chains in the radio-frequency integrated circuit to drive two pairs of radio-frequency chains in each of two connected front end modules.
