EFR32MG12 Mighty Gecko Multi-Protocol Wireless SoC Family Data Sheet
Electrical Specifications
4.1.9.1 RF Transmitter General Characteristics for 2.4 GHz Band
Unless otherwise indicated, typical conditions are: T = 25 °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 2.45 GHz.
