Periodically the topic of Adaptive Predistortion comes up for discussion on this community. Our team has been consistent in our position on this subject but sometimes it is useful to restate what has been said many times before in the interest of clarity. Here is a restatement of the facts:
The FLEX-6000 Series hardware has the necessary connections and internal RF port to port isolation to support adaptive predistortion software. We have verified that transmitter output to receiver input isolation (e.g. ANT1 to RXA) is >80 dB on all bands including 6m, which is more than ample to accommodate adaptive predistortion using an external amplifier in the loop.
FlexRadio remains interested in adaptive predistortion technology but we have not in the past nor will we now make a time frame commitment. Our internal engineering resources are 100% allocated to complete our published road map for v1.x releases through v2.0. We believe that the features committed in those releases are currently of higher priority to the vast majority of our customers than is adaptive predistortion.
- We periodically review and rank our software backlog and feature requests. We look at the ranked priorities and compare the development magnitude for each feature to the available engineering resources within a release cycle. Based on those factors, we make decisions on what features make the cut in the release planning process. So far adaptive predistortion has not made the cut. That doesn't mean it won’t make the cut in a future release.
