Can you please provide a comment regarding the increased temperature rise between the AD9361 and that of the AD9371? Is this common to have such a wide differance in temperature between the case and junction? I'm concerned that upgrading to the AD9371, which is a higher power part that the reliability will be worse.
AD9371 has an exposed die package which allows effective cooling from the Top .Customer can use heat sink to control the temperature . Maximum Junction temperature is 110 Deg C and Device is designed to operate for 10 years operating at Max Junction temperature.
