You cant beat real engineers doing their job properly. Maybe someone can email the links to some of the ham companies. Everyone whines about how hard it is to design a clean TX chain. Yet we have known about these
CATV amplifiers for years. Even the late Helge Granberg used to use these modules for ultra linear PA's, and that was 40 years ago. The ham radio markets IMD is going down to the abyss, and the opposite is happening
in the real world of engineering. Its really a poor reflection of how poor ham technical skills are becoming and nothing else. Its then no surprise we have 10,000 dollar radios with IMD performance of a truck stop CB radios.
We also have to address one of the root causes of splatter in ham transceiver designs. That is poor ALC design, and using ALC as a form of compression. We have known about this issue for years, however we still have current
model transceiver design with this issue. Very few hams can remember the days when high power SSB could be routinely heard on the air running 40 to 100kw SSB. All these commercial transmitters used tubes and the IMD performance of these systems were superb. I still have a OLD TMC transmitter driver that emits a beautifully clean signal from all this old technology. I wish I could buy a transceiver that is as clean as the old TMC driver
This CATV module driving a 50 volt FET in class A and then driving a serrated 600 watt PA, you certainly wont have a IMD issue. So easy. I know I know they prefer the RM Italy brand its da best.
In the $20 range there are even better parts (usually modules) for CATV distribution systems. Zenki would be very happy the extreme effort those guys go to, to reduce IMD to tiny tiny levels. CATV distribution guys hate the thought that anything of theirs could ever splatter.
