NPN Silicon RF Transistor
HIGH EFFICIENCY
HIGH GAIN
LINEAR AND NON LINEAR OPERATION
TRANSITION FREQUENCY 42GHz
ULTRA MINIATURE SOT343 (SC70) PACKAGE
DESCRIPTION
START499 is a product of the START family that
provide the market with a Si state-of-art RF process.
Manufactured in St 3rd generation bipolar process, it
offers the highest power, gain and efficiency in
SOT343 for given breakdown voltage (BVceo).
Suitable for a wide range of applications up to 5GHz,
it shows a performance level achieved before with
GaAs products only.
