IWR6843: customer IWR6843 board RF signal is weak

Part Number: IWR6843

Tool/software:

HI TI expert,

I designed my own board using the IWR6843 reference IWR6843ISK development board and ran the ti demo project. I found that the RF signal was very weak. I measured the RF-related VIN_13RF1, VIN_13RF2, and VOUT PA voltages, which were all normal.After checking the antenna design and processing, there were no problems. What could be the problem causing this?

    Hi,

    Could you please share your stack and antenna design? Did you follow the 50Ohm impedance matching? Also, making sure to minimise insertion loss and TX output power reflection due to impedance mismatch.

    Regards
