Does anyone have a datasheet, or any technical information at all
(frequency, power and nominal supply voltage would be adequate for my
needs I think), on this obsolete TRW transistor ?

Steve

they still have them..

Steve,

I am almost positive that this transistor (PT4370C) was used in the
Transworld RF amplifiers.
There is a Motorola MRF equivalent.
RF Parts will either have the parts or a Motorola cross reference.

Look he

If you post this question on QRZ Q&A, one of the regulars use to work at TRW
during that era - likely has the old spec sheets and any history you may
want.

No idea if this is any help at all, but...

I have a TRW data book from 1979. Doesn't list PT4370. Closest number is
PT4570. PT4570 was a wierd TO-117 case; stud mount with 4 radial leads
out of the transistor capsule. Two E leads opposite each other; C is the
one with the pointy end.

This was NPN, 40 V, fT 2GHz, dissipation 5 W.

I have no idea if this is anything similar to the one you want, but
though I'd pass the closest I found, just in case it might help.
