    Hi Deepthi,

    I think the stack-up looks ok for designing the TRF37X73 PCB.

    Hi Deepthi,

    As long as there are no spurious emissions from the device/pcb or is within the EMI/EMC regulatory requirements of the specific country, I think the PCB should be able to qualify the EMI/EMC test. This certainly includes any self-oscillatory conditions of the part. Using an EMI/EMC filter on the power supply certainly helps, along with the right power supply bypass capacitors.

    I think the stack-up you have is similar to the TRF37A73 EVM, so should be ok. You might want to take a look at the RF regulatory compliance page of the user's guide: www.ti.com/.../slau546.pdf to know what compliance tests does the EVM qualify for.

    Best Regards,
    Rohit
