Notes:
1. See PC Board Layout, page 11 for more information.
2. All components are of 0603 size unless otherwise stated.
3. Component (R1) on PCB board is a 0 Ohm jumper and can be replaced by a copper trace.
4. Critical component placement locations:
Distance from U1 Pin 1 Pad (left edge) to C6 (right edge): 45 mils (4.2º at 1850 MHz)
Distance from C6 (left edge) to C1 (right edge): 20 mils (1.9º at 1850 MHz)
Distance from U1 Pin 3 Pad (right edge) to C7 (left edge): 185 mils (17.3º at 1850 MHz)
