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.

TRANSISTOR CHIP DATA
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).

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.
