Abstract
A device includes a Doherty amplifier. The Doherty amplifier has a carrier path and a peaking path. The Doherty amplifier includes a carrier amplifier configured to amplify a signal received from the carrier path and a peaking amplifier configured to amplify a signal received from the peaking path. The device includes a resistive switch having a first terminal connected to the peaking path and a second terminal connected to a voltage reference, and a controller configured to set the resistive switch to a first resistance value when a power input of the Doherty amplifier is below a threshold and to a second resistance value when the power input of the Doherty amplifier is above the threshold.
