Hello

Any suggestions of npn low noise small signal transistors who who goes up
to arround 500 mhz ?

Thank

Bye

You need to be a LOT more descriptive about what you're trying to
accomplish.
One might interpret "who goes up to" to mean that you want broadband
performance from DC to 500MHz???
How much gain at 500MHz?
Narrow-band amplification is a lot easier...from the transistor point
of view, but still complex from the view of other parts of the system.
How low is "low noise"?

Sounds like you want a simple solution to what may be a very complex
issue. There is no easy solution to ANYTHING at 500MHz. Simple,
after you've DESIGNED it, maybe...but not easy, unless you know what
you're doing. Knowing what you're doing starts with describing what
you want to do.

Accepting the recommendation of a random transistor to solve
an unknown (to us) problem is naive.
