¹Higher data rates are achievable, depending on local regulations.

²For the definition of frequency deviation, see the Register 2—Transmit Modulation Register (FSK Mode) section.

³For the definition of GFSK frequency deviation, see the Register 2—Transmit Modulation Register (GFSK/GOOK Mode) section.

⁴Measured as maximum unmodulated power. Output power varies with both supply and temperature.

⁵For matching details, see the LNA/PA Matching section and the AN-764 Application Note.

⁶Sensitivity for combined matching network case is typically 2 dB less than separate matching networks.

⁷See Table 5 for a description of different receiver modes.

⁸Follow the matching and layout guidelines to achieve the relevant FCC/ETSI specifications.
