4.1.9.5 RF Transmitter Characteristics for Bluetooth Low Energy in the 2.4GHz Band, 2 Mbps Data Rate
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=38.4MHz. RF center frequency 2.45 GHz. Maximum duty cycle of
85%.

Note:
1. For 2472 MHz, 1.3 dB of power backoff is used to achieve this value.
2. For 2474 MHz, 3.8 dB of power backoff is used to achieve this value.
3. For 2476 MHz, 7 dB of power backoff is used to achieve this value.
4. For 2478 MHz, 11.2 dB of power backoff is used to achieve this value.
5. Per Bluetooth Core_5.0, Vol.6 Part A, 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.
