C6 should be placed at the silk screen
marker 'F' on the WJ evaluation board.
The capacitor should be placed
32.6° @ 2.14GHz from pin 1 of the AH118
Vcc = +5 V
All passive components are of size 0603 unless otherwise noted.
The diode D1 is used as over-voltage protection on the evaluation
boards. It is not specifically required in the final circuit layout in
a system using a DC regulator.
Component R1 is shown in the silkscreen but is not used for this
configuration.
L3 - the 0 ohm resistor - can be removed (with a thru line) in the
final circuit layout.
