START540
NPN Silicon RF Transistor
• LOW NOISE FIGURE: NFmin = 0.9dB
@ 1.8GHz, 5mA, 2V
• HIGH OUTPUT IP3 = 24dBm
@ 1.8GHz, 20mA, 2V
• GOOD RUGGEDNESS BVceo = 4.5V
• TRANSITION FREQUENCY 45GHz
• ULTRA MINIATURE SOT343 PACKAGE
DESCRIPTION
The START540 is a member of the START family
that provide the market with the state of the art of RF
silicon process. Manufacturated in the third
generation of ST proprietary bipolar process, it
offers the highest linearity with excellent Noise
Figure for 4.5V breakdown voltage(BVceo).
It reaches performance level only achieved with
GaAs products before.
SOT343 (SC70)
