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. The center of C3 is placed at 0.050” (5.1° @ 2.35 GHz) from the edge of the AP601 (U1).
4. The center of C19 is placed at 0.650” (66.6° @ 2.35 GHz) from the edge of the AP601 (U1).
5. The center of C30 is placed at 0.110” (11.3° @ 2.35 GHz) from the center of C19.
6. The center of C31 is placed at 0.040” (4.1° @ 2.35 GHz) from the center of C19.
7. The bold-faced RF trace is for the DC bias feed. The stub’s length is approximately a ¼ λ.
