The t ransmission 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 "F"on the
WJ evaluation board as shown.
C9 should be placed at silk screen markers "4"
on WJ evaluation board as shown.
