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.
