START499
NPN Silicon RF Transistor
* HIGH EFFICIENCY * HIGH GAIN * LINEAR AND NON LINEAR OPERATION * TRANSITION FREQUENCY 42GHz * ULTRA MINIATURE SOT343 (SC70) PACKAGE
SOT343 (SC70) ORDER CODE START499TR BRANDING 499
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.
APPLICATIONS * PA FOR DECT OR PHS * PA STAGE FOR WIRELESS LAN AND BLUETOOTH @ 2.5GHz * UHF-VHF PRE POWER AMPLIFIER

In order to avoid high complexity of the package equivalent circuit, the two emitter leads of SOT-343 package are combined in one electrical connection. FOR MORE ACCURACY SIMULATION IN SATURATION REGION : Adding the 5 Spice parameters showed in Table A and using ST Spice Library (available on request) you can achieve a more accuracy simulation in the saturation region. ST Spice library is compatible with following simulators: ELDO MENTOR (any version), SPECTRE CADENCE (any version), ADS (version 2001 only).
