Electrical Specifications

4.1.9.6 RF Receiver Characteristics for 802.15.4 O-QPSK DSSS in the 2.4 GHz Band

Unless otherwise indicated, typical conditions are: T=25 Â°C,VREGVDD = AVDD = IOVDD = 3.3 V, DVDD = RFVDD = PAVDD. RFVDD

and PAVDD path is filtered using ferrites. Crystal frequency=38.4 MHz. RF center frequency 2.445 GHz. Test circuit according to Figure

5.2 EFR32BG1 Typical Application Circuit: Configuration with DC-DC converter (PAVDD from VDCDC) on page 98 and Figure

5.4 Typical 2.4 GHz RF impedance-matching network circuits on page 100.
