Abstract
A core module for a portable computing device includes wireless power receiver circuitry, battery power circuitry, power supply circuitry, a processor, and an RF link interface. The wireless power receiver module, when operable, receives a wireless power transmit signal and converts it into a supply voltage. The battery power circuitry, when operable, outputs a battery voltage. The power supply circuitry, when operable, converts the supply voltage or the battery voltage into one or more power supply voltages. The processor is operable to select one of the battery voltage, the supply voltage, and one of the one or more power supply voltages to produce a selected voltage. The RF link interface outputs the selected voltage on to an RF link of the portable computing device for providing power to one or more multi mode RF units within the portable computing device.
