1.) Can the device be mounted on .020" RO4003 safely or will it possibly oscillate?
2.) Can you please supply the board files for your Evaluation Board?
The HMC3653LP3BE eval board uses 0.010" Rogers 4350.
We have not evaluated the part on a PCB that uses 0.020" Rogers 4003, so we have no basis on which to comment regarding the type of performance that would be obtained.
Eval board files are attached.
