I found this on Aliexpress. Does anyone have any knowledge or experience with them?

No specifically but it looks like a nice little board. Data sheet implies it will do 2W of data so I'd expect similar, perhaps a little more DATV if you don't look too closely at the shoulders. Having a circulator on the output makes it bomb-proof and based on experiments with 13cm pallets it looks like its got at least one pre-driver chip in the chain. Cheap enough although their delivery seems expensive and then its plus VAT too....
I've put one in my basket where it can sit and see if I get sent a discount.

I would stick with the Stealth Microwave units which were so cheap and readily available a few years ago. I can't see any advantage in these.

That's the problem though.....they USED to be freely available...same with the Ionica gear, supplies are drying up. We need more redundant comms infrastructure to enter the market.....
