Soldering MRF101 directly to a copper Heatsink

I am wondering if it is a good idea to solder the MRF101 to a copper heatsink spreader.  It has been done on the other larger high power LDMOS items.

Thanks

Hi TimHatch

I recommend you check the link below:

For example, at our EVK we generally do direct soldering, but for your circuit first check the recommendations and verify your values.

 

Have a great day and best of luck.
