thermal noise object RFbudget

Trying to simulate the RF budget of system which components are spaned on diffrent Temp (3k-300k), im trying to add thermal noise the the system as an element. What would be the correct way to do it?

the result system should be somthing as seen in the attached image

You can use Receiver Thermal Noise block from Communication Toolbox to specify and simulate addition of different thermal noise levels in the system.

You can refer to the RF Noise Modelling example to learn more about simulating noise in a system.
