Abstract:
A radio-frequency module includes a power amplifier, a first bias circuit connected to the power amplifier, and a second bias circuit connected to the power amplifier. The first bias circuit includes a register that receives a first digital control signal corresponding to a power mode of the power amplifier and a current generation circuit that generates, based on information in the register, a first bias current, and the second bias circuit includes another register that receives a second digital control signal corresponding to the power mode and a current generation circuit that generates, based on information in the other register, a second bias current.
