RF Power Meter AD8307

I originally set up this board to work with the circuitry in QEX article May /June 2013 by Loftur Jónasson TF33LJ/VE2LJX, “Squeeze Every Last Drop Out of the AD8307 Log Amp” pp. 29 -34.

Originally [above gerbers] L3 had 1206 pads for an 0805 part this was changed
to 0805 in the revised Gerbers below.  Also I was asked to make a two up
panelized version also a link below.  These are the only changes from files above.
