4.1.9 2.4 GHz RF Transceiver Characteristics
EFR32MG1 Mighty Gecko SoC with Integrated Serial Flash Data Sheet
Electrical Specifications
4.1.9.1 RF Transmitter General Characteristics for 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 2.45 GHz. Test circuit according to
Figure 5.2 EFR32MG1 Typical Application Circuit: Configuration with DC-DC converter (PAVDD from VDCDC) on page 64 and Fig-
ure 5.4 Typical 2.4 GHz RF impedance-matching network circuits on page 65.

Note:
1. Supported transmit power levels are determined by the ordering part number (OPN). Transmit power ratings for all devices cov-
ered in this datasheet can be found in the Max TX Power column of 2. Ordering Information
2. For Bluetooth, the Maximum TX power on Channel 2456 is limited to +15 dBm to comply with In-band Spurious emissions.
