START450
NPN Silicon RF Transistor
COMPRESSION POINT P1dB=19dBm @ 1.8GHz
TRANSITION FREQUENCY 42GHz
HIGH LINEARITY
ULTRA MINIATURE SOT343(SC70) PACKAGE
DESCRIPTION
The START450 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.
