SRFE1164 replacement

Hello,

I need to replace a couple of motorola SRFE1164 transistor in a failed
RF amplifier. There seem to be no trace of a datasheet for this
transistor on the net (motorola is the best for unknown parts afaik).
A search on google revealed that the MRF422 might be an equivalent
part. Does anyone have a datasheet for the SRFE1164? I'd hate spending
money for a matched pair of MRF422 and discovering they don't work in
the place of the unknown SRFE1164.
Thanks

There never were any data sheets. Any Motorola part with a SRF number
was a custom marked RF transistor so the OEM would be the only one who
knew what it was. You can either contact the OEM, or check with some of
the places that sell repair parts for ham radio gear. A lot of these
designs have been reverse engineered, and they know what will replace
it.

Motorola is not the only company to print OEM markings. Look at an
old IBM mainframe and see all the different IC makers with custom IBM
numbers on the parts.
