Abstract

Disclosed is an integrated circuit module that includes a first die having a plurality of hot regions and at least one cool region when operating under normal conditions. The first die with a top surface includes at least one power amplifier that resides in the plurality of hot regions. The integrated circuit module also includes a second die. The second die has a bottom surface, which is adhered to the top surface of the first die, wherein any portion of the bottom surface of the second die that is adhered to the top surface of the first die resides exclusively on the at least one cool region. In at least one embodiment, the first die is an RF power amplifier die and the second die is a controller die having control circuitry configured to control the at least one power amplifier that is an RF power amplifier type.
