Abstract:
A communication unit having a transmitter and method of harmonic distortion content reduction is described. The transmitter is configured to operate in a training mode of operation and a normal transmission mode of operation. The transmitter includes a signal generator; a digital predistortion, DPD, circuit; and a first frequency shift circuit to frequency shift a signal for transmission in a first frequency direction. A feedback path and a second frequency shift circuit frequency shifts a fed back power amplified predistorted signal portion in a second frequency direction opposite to the first frequency direction. A calibration engine, receives and compares a digital baseband signal representative of a signal for transmission with the fed back power amplified predistorted signal portion shifted in the second frequency direction to determine at least one DPD compensation value only during a training mode of operation.

Claim (Index 18):
The communication unit of  claim 16  wherein the at least one LPF is set to a first cut-off frequency in a training mode of operation and a second cut-off frequency in a normal transmission mode of operation, wherein the first cut-off frequency is higher than the second cut-off frequency.
