Old thread I know... but does anyone own one of these modules that'd be interested in taking pics or giving better detail on how it might work?
It looks like, from the picture, there's a dual and a quad op amp. Otherwise I see no obscure or less then common parts.

The Version 1 board looks to have a trimmer inductor and two additional inductors. On Version 2 and 3 boards, the trim inductor is replaced with a trim pot and I don't see any additional inductors on the board.
