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 L24 is placed at 0.090” (3.5° @ 880 MHz) from the center of C5.
4. The center of C28 is placed at 0.220” (8.4° @ 880 MHz) from the edge of the AP603 (U1).
5. The center of L4 is placed at 0.200” (7.7° @ 880 MHz) from the edge of the AP603 (U1).
6. The center of C31 is placed at 0.360” (13.8° @ 880 MHz) from the center of L4.
7. The bold-faced RF trace is for the DC bias feed. The stub’s length is approximately a ¼ λ.
8. The main RF trace is cut at component C28 and L4 for this particular reference design.
