I am using an ICOM IC-7610 transceiver and ICOM has released a software update to provide DPD (Digital Per-Distortion) in addressing non-linearity in RF power amplifiers.
Is this something which needs addressing with the Palstar LA-1K ?

Digital Pre-Distortion (DPD)?is a technique to increase linearity or compensate for non-linearity in power amplifiers.??are critical in communication systems and it is crucial to improve their efficiency and overall performance. DPD is a cost-effective linearization technique which aims to provide improved linearity, better efficiency, and take full advantage of power amplifiers.
Digital Pre-Distortion applies inverse distortion, using a pre-distorter, at the input signal of the PA to cancel the distortion generated by the power amplifier. This requires knowing the PA characteristics accurately with effective implementation for successful DPD functioning. Proper implementation can show improvements of up to 40% in PA efficiency used in wireless base stations.
