4.1.9.3 RF Transmitter Characteristics for Bluetooth Smart 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 EFR32BG1
Typical Application Circuit: Configuration with DC-DC Coverter (PAVDD from VDCDC) on page 49 and Figure 5.4 Typical 2.4 GHz RF
impedance-matching network circuits on page 50.

Note:
1. Per Bluetooth Core_4.2, Section 3.2.2, exceptions are allowed in up to three bands of 1 MHz width, centered on a frequency
which is an integer multiple of 1 MHz. These exceptions shall have an absolute value of -20 dBm or less.
2. For 2480 Mhz, a maximum duty cycle of 20% is used to achieve this value.
