5.6. RF Characteristics (Design Target Values)

The RF characteristics are based on the following conditions, unless otherwise specified.



Ta = 25 °C



VBAT = 3.0 V



XOIN = 32 MHz (The frequency accuracy should be adjusted to ±2 ppm at room temperature)



PAOUT = 8 dBm

Table 5-8 shows the RF transmission characteristics which are compliant with the Bluetooth® Core Specification Version 5.0

standard. Table 5-9 shows the RF reception characteristics. Some values in those tables are design target values.
