Abstract
An apparatus is disclosed for frequency-based predistortion signal generation. In an example aspect, the apparatus includes a predistortion linearizer circuit configured to be coupled to an input of an amplifier. The amplifier has non-linearities associated with multiple frequencies. The multiple frequencies include a first subset of frequencies and a second subset of frequencies. The predistortion linearizer circuit is also configured to accept an input signal. The predistortion linearizer circuit is additionally configured to generate, based on the input signal, a compensation signal to attenuate the non-linearities existing within the first subset of frequencies more than the non-linearities existing within the second subset of frequencies. The predistortion linearizer circuit is further configured to generate a pre-distorted signal based on the input signal and the compensation signal.
