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%.
