What is the phase relationship between two PoAs on the dw3220？

Wireless Connectivity Ultra-Wideband

There is a phase rotation that occurs internally when calculating PDoA between STS1 and STS2 using mode 3.
Change to Mode 1, and use IP_POA - STS_POA.
Or if you need to use mode 3, you can set the CIA_ADJUST register = 0.
