Directional coupler detail

Is there any documentation on the directional coupler? It looks like some kind of large ferrite over part of the board, but I can't see any information other than that the PCB has a stripline.

it's a resistive bridge plus a balun, similar to the coupler used here: http://hforsten.com/improved-homemade-vna.html
