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 SOT343 (SC70) ORDER CODE START420TR BRANDING 420 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.
