Infineon RF Transistors SPICE library converted for QUCS Studio

In the SPICE and Models section of this site, you will find the QUCS Studio compatible models for the RF bipolar transistor library published by INFINEON in their website. The transistors are included in a project and they are the following:

*     BFP181              BFP620F             BFP843              
*     BFP182W             BFP640              BFP843F             
*     BFP183              BFP640ESD           BFQ19S              
*     BFP183W             BFP640F             BFQ790              
*     BFP193              BFP640FESD          BFR106              
*     BFP193W             BFP650              BFR181W             
*     BFP196              BFP720              BFR182              
*     BFP196W             BFP720ESD           BFR182W             
*     BFP405              BFP720F             BFR193F             
*     BFP405F             BFP720FESD          BFR193W             
*     BFP410              BFP740              BFR340F             
*     BFP420              BFP740ESD           BFR35AP             
*     BFP420F             BFP740F             BFR380F             
*     BFP450              BFP740FESD          BFR740L3RH          
*     BFP460              BFP750              BFR840L3RHESD       
*     BFP520              BFP760              BFR843EL3           
*     BFP540              BFP780              BFR92P              
*     BFP540ESD           BFP840ESD           BFR93A              
*     BFP540FESD          BFP840FESD          BFR93AW             
*     BFP620              BFP842ESD

Along with the models test files are included in the project in order to get an idea of what are the shape of the DCDC curves of each transistor.

It is important to note that several models have convergence issues during the DCDC analysis, that are currently under investigation.

    I think some of your models have errors. QucsStudio 3.3.2 generates slightly different models than 2.5.7. For example the BFP420 Spice model uses a transistor with a substrate connection. QucsStudio 3.3.2 has it but 2.5.7 doesn't.

    Thank you very much for sharing this information. In fact these models come from the vendor. The only thing that I have done is to make them available to be used in QUCS Studio.
    In any case it is very interesting to know these kind of details, because all of this stuff worths if it is useful and accurate.
    I will have a look to this issue and I will try to adapt the models to the new enviroment in QUCS Studio 3.3
    Thanks again and best regards.
