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 0.875” (81.6
°
@ 2140 MHz) from the center of C5.
5. The center of C5 is placed at 0.070” (6.5
°
@ 2140 MHz) from the edge of the AP603 (U1).
6. The center of C28 is placed at 0.190” (17.7
°
@ 2140 MHz) from the edge of the AP603 (U1).
7. The center of C29 is placed at 0.300” (28.0
°
@ 2140 MHz) from the center of C28.
8. The bold-faced RF trace is for the DC bias feed. The stub’s length is approximately a
