    Richard,

     It is possible that the device could overheat at higher frequencies and the tool is limiting the change. Can you share your exact design conditions so i can try and reproduce this case?

    Regards,

    Richard,

    It seems you tried to send an attachment but i did not get it. Could you use the 'Insert File' option to attach and resend?

    Thanks.
