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.
