A basic application schematic of the AT86RF212 with a single-ended RF connector is
shown in Figure 3-1. The 50 Ω single-ended RF input is transformed to the 100 Ω
differential RF port impedance using balun B1. The capacitors C1 and C2 provide AC
coupling of the RF input to the RF port. Regulatory rules like FCC 47 CFR section
15.247 [4], ETSI EN 300 220-1 [5], and ERC/REC 70-03 [6] may require an external
filter F1, depending on used transmit power levels.
The power supply bypass capacitors (CB2, CB4) are connected to the external analog
supply pin (EVDD, pin 28) and external digital supply pin (DEVDD, pin 15). Capacitors
CB1 and CB3 are bypass capacitors for the integrated analog and digital voltage
regulators to ensure stable operation. All bypass capacitors should be placed as close
