    摘要: An embodiment of the present invention provides a RF power amplifier. The RF power amplifier comprises an RF input distribution network, multiple amplifiers and a signal combining network. The RF input distribution network is configured to divide an input RF signal into a main input signal and an auxiliary input signal. The multiple amplifiers are coupled in parallel to the RF input distribution network and configured to amplify the main and auxiliary input signals respectively by a main amplifier contributing a larger portion of the output power of the RF power amplifier and an auxiliary amplifier contributing a smaller portion of the output power of the RF amplifier. Each of the main and auxiliary amplifiers is selected from the amplifiers according to an impedance ZL of the transmit coil. A loading level of the main amplifier is modulated to alleviate loading mismatch condition of the main amplifier by adjusting current contributions from the main amplifier and the auxiliary amplifier according to the impedance ZL of the transmit coil. The signal combining network is configured to combine the main amplified signal and the auxiliary amplified signal into an output signal to drive the transmit coil.

    摘要: An electronic device includes a power supply, a heat generating module, a detecting module, a switching module presetting a predetermined voltage, and a heat dissipation module. The heat generating module is powered by the power supply to generate heat. The detecting module detects the heat of the heat generating module and generates a control voltage variable with the heat of the heat generating module. The switching module establishes the electrical connection between the power supply and the heat dissipation module when the control voltage is smaller than the predetermined voltage and generates a working voltage variable with the control voltage. The heat dissipation module is powered by the working voltage to dissipate the heat of the heat generating module with different heat dissipation efficiency. The heat dissipation efficiency is variable with the working voltage.
