Re: On the subject of fake IRF510
I find this post from Allison to be informative, she definitely knows what she's doing:toggle quoted messageShow quoted text
There are issues with the IRF510 as an RF amp.
Primary issue is poor thermal conductivity from die to TO-220 tab.
Also, the tab is connected to the drain, not the source as it would be in a good RF device,
so be careful not to short the heatsink to ground! (Or add a $0.05 mica insulator and heatsink paste.)
The IRF510 does work better at 24v than at 12v, giving better linearity.
But otherwise, Allison reports that the IRF510's behavior is similar to
the 10x more expensive RF devices such as the RD16HHF1.
She continues to use the IRF510.
