1 Using 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.

2 Using raised cosine filtering with an alpha = 0.7. The inner frequency deviation = 1.78 kHz, and the POST_DEMOD_BW = 24.6 kHz.

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

4 Measured as maximum unmodulated power.

5 Conductive filtered harmonic emissions measured on the EVAL-ADF7021DBx, which includes a T-stage harmonic filter (two inductors and one capacitor).

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