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.

thank you.
