EFR32BG1 Blue Gecko Bluetooth® Smart SoC Family 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 EFR32BG1 Typical Application Circuit: Configuration with DC-DC converter (PAVDD from VDCDC) on page 98 and Fig-
ure 5.4 Typical 2.4 GHz RF impedance-matching network circuits on page 100.

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.
