AWR1843AOPEVM: PCB ground near the chip

Hello,

Thank you for reaching out to Texas Instruments. There is no GND next to the device as this is an AOP device and surface wave artifacts can interfere in the radiation pattern. This is mentioned more in the device errata. https://www.ti.com/lit/er/swrz115a under PACKAGE02A Advisory. 

Hope this helps,
