MMWCAS-RF-EVM:   MMWCAS-RF-EVM 中：MMWCAS-RF-EVM TX phase shifter compensation

Hi,

I am trying to use MMWCAS-RF-EVM for TX beamforming. Before that, I followed the steps in the <AWRx_TX_Channel_Calibration_Script_User_Guide.pdf> to calibrate the transmit phase shifter. It can be seen that when the phase shifter of each transmit antenna is configured at 0 deg, the peak phase of the angle is different.

Why is the phase shifter configuration of each transmit antenna 0 when beamforming at 0deg in the final generated LUT? Doesn't it need compensation?

thanks,

Hanchen Li
