These class d audio-amps are getting cheaper and cheaper...
Using one of this modules as a power supply for an LF/MF class d rf-amp could be an interesting idea:

Oops ! Sorry. Link included now

This site has a design with the TPA3151D2 http://www.360customs.de/en/2015/07/tpa3251d2-2-x-175w-stereo-350w-mono/

At the bottom there is a chat and some people asked about PCBs

The answer is: If you want to build one up for yourself, pcbs are available.

But no further information. You can contact with the author for details
