Notes:

1. The primary RF microstrip line is 50 Ω.

2. Components shown on the silkscreen but not on the schematic are not used.

3. 0 Ω jumpers can be replaced with copper trace in target application.

4. Distance from side edge of C10 to side edge of U1 pin 1 is 55 mils (7.9° at 2600

MHz).

5. Distance from end edge of R1 to side edge of U1 pin 1 is 110 mils (15.8° at 2600

MHz).

6. Distance from side edge of C9 to side edge of U1 pin 3 is 90 mils (13.0° at 2600

MHz).
