DESCRIPTION
The START405 is a member of the START family
that provide the state of the art of RF silicon process
to the market. Manufacturated in the third
generation of ST proprietary bipolar process, it
offers the best mix of gain and NF for given
breakdown voltage(BVceo).
It offers performance level only archived with GaAs
products before.
