Hi,
I want to simulate and test a RF IC. its large signal model without layout is available on the producer website. how can I do thermal simulation on this IC? no further file is available except that large signal model. in fact, I want to do thermal simulation on the test circuit which uses this IC. I have attached the microwave test circuit schematic.

It's generally difficult to predict thermal response of such application circuit because you don't know all the details about package, substrate, heatsink etc. RFIC or MMIC circuits are easier for predicting thermal effect because almost all layer specifications are readily available.
All you can do is to measure the thermal vision of the board.
