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 0.035” (3.0
°
@ 1960 MHz) from the center of C5.
4. The center of C5 is placed at 0.085” (7.3
°
@ 1960 MHz) from the edge of the AP601 (U1).
5. The center of C19 is placed at 0.755” (64.5
°
@ 1960 MHz) from the edge of the AP601 (U1).
6. The center of C18 is placed at 0.300” (25.6
°
@ 1960 MHz) from the center of C19.
7. The bold-faced RF trace is for the DC bias feed. The stub’s length is approximately a
λ
.
8. The main RF trace is cut at component location L3 for this particular reference design.
