Apparatus and method for linearizing narrowband carriers with low resolution predistorters are provided. The method includes amplifying, using a power amplifier, one or more broadcast carriers and linearizing, using a predistorter coupled to the power amplifier, the one or more broadcast carriers. The method also includes determining, using an electronic processor, a composite bandwidth of the one or more broadcast carriers and determining, using the electronic processor, whether the composite bandwidth is below a modulation bandwidth of the predistorter. The method further includes controlling, using the electronic processor, a pacification carrier generator coupled to the electronic processor to combine a pacification carrier with the one or more broadcast carriers when the composite bandwidth is below the minimum modulation bandwidth of the predistorter.
