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 C22 is placed at 0.185” (17.3° @ 2140 MHz) from the center of C1.
4. The center of C1 is placed at 0.910” (84.9° @ 2140 MHz) from the center of C3.
5. The center of C3 is placed at 0.035” (3.26° @ 2140 MHz) from the edge of the AP602 (U1).
6. The center of C6 is placed at 0.510” (47.6° @ 2140 MHz) from the edge of the AP602 (U1).
7. The bold-faced RF trace is for the DC bias feed. The stub’s length is approximately a ¼
λ.
