DWM1000 Bandwidth setting


How to change the bandwidth settings. Default TC_PGDELAY value for channel 5 is 0xC0. This will give 499MHz. I need to set the bandwidth as 400MHz. What value, Ineed to program into TC_PGDELAY register for getting 400MHz Bandwidth?

Hi Shijo,
I can’t say exactly what setting will give a reduced bandwidth of 400 MHz but you can observe the transmit spectrum on a spectrum analyser and increase the PGDELAY value until you get the desired bandwidth.

The FFC defines UWB as any signal that occupies more than 500 MHZ in the 3,1-10,6GHz range.
A. Alarifi et al., “Ultra Wideband Indoor Positioning Technologies: Analysis and Recent Advances,” Sensors, vol. 16, no. 5, p. 707, 2016.

Why you want decrease the bandwidth?
I’m learnig.

This is required if we are using ultra wide band for outdoor applications in United states.

Ok, i didn’t know that.
Thank you for reply.
