Claim Text:
1. The radio frequency (RF) system control circuitry comprising a baseband power amplifier (PA) predistortion module, which comprises: a baseband PA correction circuit configured to replicate behavior of an RF PA by processing a modulation data signal to provide a predistortion data signal, wherein: a high pass baseband filter configured to receive and filter the predistortion data signal to provide a reduced predistortion data signal, wherein a low frequency content of the reduced predistortion data signal is less than a low frequency content of the predistortion data signal, and a break frequency of the high pass baseband filter is based on a transmit/receive offset frequency; and a baseband combiner configured to receive and combine the modulation data signal and the reduced predistortion data signal to provide a baseband transmit signal.
