1. See PC Board Layout, page 11 for more information.
2. The recommended component values are dependent upon the frequency of operation.
3. Component (R1) on PCB board is a 0 Ohm jumper and can be replaced by a copper trace.
4. All components are of 0603 size unless stated on the schematic.
5. Critical component placement locations:
Distance from U1 Pin 1 Pad (left edge) to C5 (right edge): 55 mils (5.5º at 1960 MHz)
Distance from C5 (left edge) to C1 (right edge): 10 mils (1.0º at 1960 MHz)
Distance from U1 Pin 3 Pad (right edge) to C6 (left edge): 125 mils (12.4º at 1960 MHz)
