DESCRIPTION

The START450 is a member of the START family that

provide the state of the art of RF silicon process to the

market. 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 offers performance level only archived with GaAs

products before.

APPLICATIONS

• LNA FOR GSM/DCS, DECT, PCS, PCN,

CDMA, W-CDMA

• PREDRIVER FOR DECT

• GENERAL PURPOSE 500MHz-5GHz

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).
