IWR1443: IWR1443 Rx gain mismatch variation from chip to chip and Tx power variation from chip to chip?

Hello,

Thank you for reaching out to Texas Instruments. The IWR1443 Rx gain mismatch variation from chip to chip will be stable with very slight variations. And Tx power variation from chip to chip should be stable as well 

Hope this helps,

You do not answer my question, my question is the Gain difference from chip to chip!!!
