Hi. I'm using ADRF6516 in our transceiver.
The module consist of 4 layer of PCB.
The chip operating well. but, thermal problem ouccured..
In my opinion, chip's high current consumption is the problem.
So, I formed the via-hole on the exposed paddle of chip, referring the datasheet. (The via-hole has 13mil diameter. )
and I connected the exposed paddle to a ground plane(Second layer).
but, still i couldn't solve this problem.
I wonder how to solve this severe problem. if it is possible, I'd like to purchase the ADRF6516 Evaluation board.
I failed to purchase the Evaluation board on the Analog device Website..
Please help me solve this problem.
