RFblocksethas specific RF blocks which has the required noise modelling. In other words, they do not have component level or device level models.
Explicit way formodelling the thermal noise ofa resistor is shown inthis documentwith an example where the current model is used to generate a noise current which is connected in parallel to the resistor. Refer to the documentation of theNoise blockfor more details.
The noise models for transistors can be implementedsimilarly byusing the noise blocks for noise simulation of ideal transistors if required.
