The transmission line lengths are from the edge of the device

pins to the center of the component.

All passive components 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.
