Re: mounting power IMFETS ?

I seem to recall that the 10GHz Qualcomm amplifier pcb transistors had
silicon heat transfer paste on them.

Subject: [ukmicrowaves] mounting power IMFETS ?

Hi all,

A quick question on mounting uWave IMFETS. I'm building 10GHz PA's and
wonder about the use of silicon heat transfer paste under the FETs.
Some articles I've read on the net say its ok, others say its not.
Reasons for not using it is because it may prevent proper RF grounding

Any wise words for me?

cheers all,

Paul M0EYT.
