¹Using Gaussian or raised cosine filtering. The frequency deviation should be chosen to ensure that the transmit-occupied signal bandwidth is within the receiver

IF filter bandwidth.

²For the definition of frequency deviation, refer to the Register 2—Transmit Modulation Register section.

³Measured as maximum unmodulated power.

⁴Conductive filtered harmonic emissions measured on the EVAL-ADF7021-NDBxx, which includes a T-stage harmonic filter (two inductors and one capacitor).

⁵For matching details, refer to the LNA/PA Matching section.
