Well since the Toshiba 2879 and 2290 are extinct.

Check out what this builder is doing to fill the Gap of the extinct Toshiba transistor.. I like what I see so far.

I don't know anything about BBi, but that's exactly where it's headed. Pretty exciting actually.

I don't believe anything that comes out of his mouth. His boxes magically make more watts than anyone else.........

He's something else, that's for sure.

LDMOS is the future of high power RF. There are already single devices that produce 1200 watts. 50 volts just makes it a bit harder to run in a mobile application but easier for a base.

I was thinking the same thing, CK.
Just cannot remember that part #. We had a thread or three on the forum about it over the last couple of years IIRC. The heat sink for it would be an issue that would need a lot of attention.

That's why BBi is on the case.

It is not new, these devices have already been around for a while.
Not only do the produce very good gain, they are damn near bullet proof.
If you search here on the forum there is a vid showing a kw device with the output shorted with a large screwdriver at full output.
Even after that kind of abuse it was fine.

Like I have always said, if you can't dazzle them with your brilliance then baffle them with your bullshit.

Can I venture a guess that BBI is located in a Medical Marijuana state?

The Toshiba 2879 and 2290s are extinct????????? NO THEY AREN'T......but they aren't $21 a piece any more.

No, not quite extinct but getting close ...... I would say somewhere between EW (extinct in the wild) and CR (critically endangered).
