Abstract:
1. An amplification unit, comprising: a first amplifier, wherein the first amplifier is operable to amplify a first signal to produce a second signal; a first sensor, wherein the first sensor is operable to produce a third signal based on the second signal; a second amplifier, wherein the second amplifier is operable to turn on and to amplify a fourth signal to produce a fifth signal when the amplitude of the fourth signal exceeds a threshold amplitude and to turn off when the amplitude of the fourth signal is less than the threshold amplitude; a first predistortion component, wherein the first predistortion component is operable to produce the first signal based on a first input signal, based on the third signal, and based on an on-off state of the second amplifier; and a signal combiner, wherein the signal combiner is operable to produce an output of the amplification unit based on the second signal and the fifth signal.
