I am working on a thermal analysis for a board that uses HMC441LM1. The values used for the calculations are junction-to-case resistances and junction-to-board resistance (or just junction-to-case if junction to board is not available). IN the data sheet it only lists the thermal resistance for junction-to-ground paddle. I'm not sure if I can use this in my calculations. Can someone please provide the junction-to-case resistance?
