4.1.9.4 RF Receiver Characteristics for Bluetooth Smart in the 2.4 GHz Band
Unless otherwise indicated, typical conditions are: T_OP = 25 °C,VREGVDD = AVDD = IOVDD = 3.3 V, DVDD = RFVDD = PAVDD.
RFVDD and PAVDD path is filtered using ferrites. Crystal frequency=38.4MHz. RF center frequency 2.440 GHz. Test circuit according
to Figure 5.2 EFR32MG1 Typical Application Circuit: Configuration with DC-DC converter (PAVDD from VDCDC) on page 64 and
Figure 5.4 Typical 2.4 GHz RF impedance-matching network circuits on page 65.
