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).

APPLICATIONS

• LNA FOR GSM/DCS, DECT, PDC, PCS,

PCN

• PREDRIVER FOR DECT

It reaches performance level only achieved with

GaAs products before.

• 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).
