2.4 GHz linear board....

2.4 GHz linear board from ebay came today:

This is what the PCB looks like:

And this is the other side, the copper bottom heat spreader, PCB and heatspreader are one thing:

It is an interesting board, the transitors (MOSFETS) seem to be a special issure of the MRF286, datasheet says ' pilot production prototype'...

The good thing is the trimers, on side of the push-pull with solder stripes, opposite site with a real trimmer, need to shift this from 2.3something GHz to 2.4...

Bias pots for the MOSFETS, temp sensor outputs....

Proof that it is all possible is already done, somebody beat me to it:

Note the metal frame to push the heat spreader against the heatsink.

More parts came in.. ceramic filters for about 1 GHz...

Oh my, that means 28 have been---- violated.

However, I think the number should be 72.

Is there not a group for comedians?

My response was meant to be as humorous as the post to which I was responding. Perhaps I misjudged. I apologize.

Context/nuance is often not conveyed in text, so no big deal. May be one reason emoticons were invented and useful. A smiley face would have made your comment different, no matter how juvenile it makes you feel. :-) Mikek

I know, Mike, but I have a problem remembering to add the emoticons as well as which one I should use. Sorry about that, too.

How about a bald head and sad? (:(

And I understood it that way. The part about insults referred to other discussions in this group.
