IWR6843: sharing single antenna

Part Number: IWR6843

Team, 

Is there an approach that you can share for sharing a single antenna for RX and TX ? (in the case where only one RX and TX is required). I know it is difficut for FMCW but can be helpful for when considering small lens design. 

Thanks !

  • Hello Notozman,

    Currently, there are no reference design available in TI. However using Rat race or similar coupler could be used to build a mono-static radar. 

    There are some literature (not many though) shown in the below paper which uses rat race coupler to demonstrate this concept.

    In this paper differential to single ended configuration is used, but TI mmWave sensors are single ended output hence differential to single ended design is not needed, therefor coupler design would be simpler.
