    摘要: Radio frequency (RF) power amplifier (PA) circuitry, which transmits RF signals is disclosed. The RF PA circuitry includes a final stage, a final stage current digital-to-analog converter (IDAC), and a final stage temperature compensation circuit. A final stage current reference circuit may provide an uncompensated final stage reference current to the final stage temperature compensation circuit, which receives and temperature compensates the uncompensated final stage reference current to provide a final stage reference current. The final stage IDAC uses the final stage reference current in a digital-to-analog conversion to provide a final stage bias signal to bias the final stage. The temperature compensation provided by the final stage temperature compensation circuit is selectable.

    摘要: A power amplifier (PA) controller semiconductor die and a first radio frequency (RF) PA semiconductor die are disclosed. The PA controller semiconductor die includes a first electro-static discharge (ESD) protection circuit, which ESD protects and provides a first ESD protected signal. The RF PA semiconductor die receives the first ESD protected signal. In one embodiment of the PA controller semiconductor die, the first ESD protected signal is an envelope power supply signal. The PA controller semiconductor die may be a Silicon complementary metal-oxide-semiconductor (CMOS) semiconductor die and the RF PA semiconductor die may be a Gallium Arsenide semiconductor die.
