IWR1443: improve the isolation

liu liu

Part Number: IWR1443

Hi, I have two questions：

1. The antenna form of our products is the community antenna. But the antenna isolation cannot meet our requirements. I heard that TI company has a calibration method that can improve the isolation between the receiving andTransmitting ports. Can you provide to me?
2. I heard that TI company has improve the signal to noise method like coherent accumulation，Can you provide the correspond material to me?

Thank you !

Hello,

Antenna isolation is one of the design criteria in the PCB and Antenna design.

TIDEP-0091 reference design | TI.com

You could refer to above design guide for coherent accumulaiton.

You could also review the SNR improvement using coherent accumulation at the cost of higher processing/power trade-offs from the below link provided in the above TI desing.

For the Antenna & system calibration you could refer below link
