This paper proposes a new analog predistorter
configuration and states the reduction in distortion components suppression performance caused by the ripple of the
bandpass filter used to compensate frequency-dependent distortion components, as well as methods
to mitigate this reduction. Simulation results show
that compensating distortion based on the median
value of the ripple can mitigate the reduction in
distortion components suppression performance.
