Electrical Specifications
4.1.9.2 RF Receiver General Characteristics for the 2.4 GHz Band
Unless otherwise indicated T=25C,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 EFR32FG1
Typical Application Circuit: Configuration with DC-DC Coverter (PAVDD from VDCDC) on page 48 and Figure 5.4 Typical 2.4 GHz RF
impedance-matching network circuits on page 49.
