Abstract

A device (500) includes an amplifier (503) having a first path (523) and a second path (517) and a first variable attenuator (521) connected to the first path. The device includes a controller (527) coupled to the first variable attenuator. The controller is configured to determine a magnitude of an input signal (507) to the amplifier. When the magnitude of the input signal is below a threshold, the controller is configured to set an attenuation of the first variable attenuator to a first attenuation value. When the magnitude of the input signal is above the threshold, the controller is configured to set the attenuation of the first variable attenuator to a second attenuation value. The second attenuation value is less than the first attenuation value.
