DESCRIPTION
The START420 is a member of the START family
that provide market with the state of the art of RF
silicon process. 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 reaches performance level only achieved with
GaAs products before.
