Electrical Specifications

4.1.9.3 RF Transmitter Characteristics for 1Mbps 2GFSK in 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 2.44 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.
