Notes:
1. The primary RF microstrip line is 50 Ω.
2. Do not exceed 5.5V on Vpd or Vcc or damage to D1 will occur.
3. Components shown on the silkscreen but not on the schematic are not used.
4. C1 & C12 can be replaced with a copper trace.
5. 0 Ω jumpers can be replaced with copper trace in target application.
6. The edge of C17 is placed 55 mil from the AH420 RFin pin. (7.1o @ 2.35 GHz)
7. The edge of C14 is placed 70 mil from the edge of C17. (9.0o @ 2.35 GHz)
8. The edge of C13 is placed 55 mil from the AH420 RFout pin. (7.1o @ 2.35 GHz)
9. The edge of C15 is placed 70 mil from the edge of C13. (9.0o @ 2.35 GHz)
