My design requires a distance of about 4-5 feet between the host microcontroller and the UWB transceiver. I’m considering using the LTC6820, which offers isolated SPI data communication at rates up to 1 Mbps, easily handling distances of up to 10 meters. Do you foresee any issues with this approach, and what is the minimum SPI bus speed required to communicate with the DWM3001?
In terms of DWM3001C SPI communication the driver is set for either 1 Mbps or can be set to a higher speed of 8 Mbps the only concern would be the timing of the LTC6820 of having a maximum rate of 1 Mbps. To be comfortable you would probably want something with a higher maximum rate (at least 2 Mbps).

Thank you James. This is good information. Either I have to find a different IC or use some sort of repeaters.
By any chance, is there any Qorvo UWB transceiver that supports UART with host?
Currently I’m afraid not, only SPI.
Thank you James, appreciate your help here!
@gaurav , perhaps you can use the DWM3001C module or Murata Type 2AB Module instead of the just the transceiver. Both of those modules have a microcontroller inside so then you can use UART from the module to your Host MCU.
