Abstract:
Metal pillars are placed adjacent to transistor arrays in the power amplifiers that can be used in wireless devices. By placing the metal pillars in intimate contact with the silicon substrate and not over a substantial portion of the transistor arrays, the heat generated by the transistor arrays flows down into the silicon substrate and out the metal pillar. The metal pillar forms a solder bump of a flip chip power amplifier die, which when soldered to a module, further conducts the heat away from the transistor array.

Claim (Index 1):
A wireless mobile device comprising:\n an antenna configured to receive and transmit radio frequency signals; a transmit/receive switch configured to pass an amplified radio frequency signal to the antenna for transmission; and a multi-chip module including a flip chip amplifier die that includes at least one emitter-ballasted amplifier configured to amplify a radio frequency input signal and to generate the amplified radio frequency signal, the at least one emitter-ballasted amplifier including at least one transistor formed over and in thermal communication with a silicon substrate, a first resistor in communication with an emitter of the at least one transistor to form at least one emitter-ballasted transistor of the emitter-ballasted amplifier, and a metal pillar formed adjacent to the at least one emitter-ballasted transistor, in electrical communication with the first resistor, and in thermal communication with the silicon substrate, and an output matching network die including an output matching network circuit configured to match an impedance of a fundamental frequency of the amplified radio frequency signal.
