Abstract
The present application provides a multimode transmit power control loop, an electronic device, and a method of adjusting a detected operating level of amplified power output from a power amplifier. The multimode transmit power control loop including a feedback path wherein a feedback path signal is coupled to a feedback detection input of the power amplifier via the feedback path. The feedback path includes a mode selection switch having a control input for selectively applying a different impedance circuit to the feedback path for switching in different attenuation levels, based upon the control input of the mode selection switch identifying one or more of multiple potential operating modes. Operation of the multimode transmit power control loop increases or decreases an operating level of amplified power output from the power amplifier, which is proportional to a present level of attenuation resulting from the particular impedance circuit being applied to the feedback path via the mode selection switch.
