Looks like Broadcom is killing off all the Avago e-phemts.
Fast discretes are going away.

I met a chip designer on the web who used to work for AD. I asked semi-jokingly if they could make a MAT-02 on steroids, in that thermally enhanced SO-8 with the belly contact.
No way. Instead, the MAT-02 is gone also. :-(
For fast PNP, that leaves us with the Intersil arrays.
<And I can get them space-proof. That would be the next hurdle.

There are a fair number of medium-fast PNPs from Rohm, On, Panasonic, NXP, and Nexperia, but no SOT89's (all SOT23 or similar) and nothing above about 1.5 GHz.
Bummer.
I might experiment with novel heat sinking of some SOT23's.
Or I could maybe buy bare chips and have a packaging outfit make them into SOT89s for me.

The speed is mostly a matter of running them hot and getting the heat out?
Is it to late for some life-time buy? We bought a life time of laser diodes (~7-10 years ago, ~$10ea) And I've seen them for $1 on ebay.. I should throw ~4100 at some and try them.

The parasitic resistances of those are fairly horrible though.

We tried that for some obsolete power parts. They were remarked devices, it was a different device in the same package.
