2. Components shown on the silkscreen but not on the schematic are not used.
3. The center of C22 is placed at 0.185” (17.3
°
@ 2140 MHz) from the center of C1.
4. The center of C1 is placed at 0.860” (80.2
°
@ 2140 MHz) from the center of C5.
5. The center of C5 is placed at 0.085” (7.9
°
@ 2140 MHz) from the edge of the AP603 (U1).
6. The center of C23 is placed at 0.245” (22.9
