START420

NPN Silicon RF Transistor

• LOW NOISE FIGURE: NFmin = 1.05dB

@ 1.8GHz, 5mA, 2V

• COMPRESSION P1dB = 12.5dBm

@ 1.8GHz, 20mA, 2V

• ULTRA MINIATURE SOT343 PACKAGE

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.

SOT343 (SC70)
