ANA#39

HPF cutoff frequency 2800kHz configuration can result in incorrect RX IFA gains and filter corner frequencies.

Revisions Affected

IWR2944 ES1.0, ES2.0

Details

The analog IF stages include a second order high pass filter that can be configured to the following -6dB corner frequencies :

300, 350, 700, 1400, 2800 KHz.

Out of these, HPF cutoff frequency 2800kHz configuration can result in incorrect RX IFA gains and filter corner frequencies.

Workaround

Use of 2800kHz cutoff configuration is not recommended.
