The t ransmission line lengths are f rom the edge of the device
pins t o the center of the component.
All passive component s are size 0603 unless otherwise noted.
C8 should be placed at silk screen marker "D"on the
WJ evaluation board.
C9 should be placed between silk screen markers "4"
and "5" on WJ evaluation board.
