Abstract
An amplifier circuit is disclosed. In one embodiment, the amplifier circuit includes an input configured to receive an input signal. The amplifier circuit further includes an amplifier connected to the input that is configured to receive the input signal and generate a modulated input signal based on the input signal and one of a first amplification level and a second amplification level. The amplifier comprises a first transistor configured to receive the input signal and a second transistor connected in cascode with the first transistor. The amplifier circuit further includes a switching component configured to switch the amplifier between the first amplification level and the second amplification level. The amplifier circuit still further includes an output connected to the amplifier and configured to output the modulated input signal.
