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 C1 is at 0.710” (29.1
°
@ 940 MHz) from the center of C24.
4. The center of C24 is placed at 0.285” (11.7
°
@ 940 MHz) from the edge of the AP601 (U1).
5. The center of C26 is placed at 0.055” (2.3
°
@ 940 MHz) from the edge of the AP601 (U1).
6. The center of L4 is at 0.095” (3.9
°
@ 940 MHz) from the center of C26.
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 components L3 and L4 for this particular reference design.
