Please let me know the following data of HMC948LP3E and HMC532LP4E.
<Need Information> - theta-JA - theta-JC
For legacy HMC products like these, theta-JA was not derived. It's pretty useless (my opinion) as this is not the primary thermal path and generally derived using a JEDEC board that is not representative of the actual application. The JEDEC board will not match the recommended board thickness, material, footprint, etc. - only somewhat useful for comparing thermals to the same product that a competitor may offer in the same package.
Theta-JC = Thermal Resistance (junction to ground paddle) on the HMC532.
