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 L3 is placed at 0.095” (8.1
°
@ 1960 MHz) from the center C2.
4. The center of C2 is placed at 0.135” (11.5
°
@ 1960 MHz) from the edge of the AP602 (U1).
5. The center of C30 is placed at 0.580” (49.6
°
@ 1960 MHz) from the edge of the AP602 (U1).
6. The bold-faced RF trace is for the DC bias feed. The stub’s length is approximately a
λ
.
7. The main RF trace is cut at component location L3 for this particular reference design.
