CC1352R: Using WB modulation to pass FCC part 15.247 Digital Modulation

Nathan Marion

Part Number: CC1352R

We have moved from LRM to WB modulation to pass FCC, Can you please verify this will meet FCC Occupied Bandwidth requirement and is greater than 500KHz?

Hi, The signal is not wideband, looks like your 6 dB bandwidth is 440 kHz.

Correction, this was the freq delta from Marker 2 to Marker 1.

6dB bandwidth is 440 + 100 kHz = 540 kHz

Hi RGW,

Need to add delta 2 and delta 3 together, I get 540KHz, do you agree?

Hi,

Yes, agree that Marker 3 is at +440 kHz and Marker 2 at - 100 kHz; then the 6 dB bandwidth is 540 kHz.
