    Hi,

    Yes, it looks OK.

    I observed that some of the De-Coupling Caps on Power Supply pins of CC1312R are not Grounded and also Pin-24 shorts to Gnd plane.

    Please run DRC to determine for any shorts or any other issues with the nets.


    Thanks,

    Hello,

    here i have attached 2 image, one is from our own new pcb design of CC1310 & second is from CC1310 reference design which we refer.

    there are two difference between our new design & CC1310 reference design as:

    1) from Antenna connector horizontal gnd plane is 11.66mm in reference design & 5.7mm in our new design.

    2) from Antenna connector vertical gnd plane is 5.35mm in reference design & 3.9mm in our new design.

    is this difference affect on our new pcb design RF range & performance.?

    & second thing i need to ask is that,  in our pcb design as it seems in image i have attached, out of 4 GND pin of Antenna connector, 2 pin are not fully cover by GND plane, is it affect Our RF performance.?

    also, whether Antenna connector 4 GND pin need direct short with GND Plane or need to place fork.? if need to place fork than how many fork need to place &  what will be the width of the fork track.?

    Hi,

    It seems you are going to use a Whip Antenna.
    Yes, Gnd plane will influence the Radiation pattern. But in this case, I expect the affect will be minimal.
    I recommend to test the Range on your prototype boards.

    Thanks,
