ELECTRONIC DEVICE FOR TRANSMITTING RADIO-FREQUENCY SIGNAL AND METHOD FOR OPERATING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17880527 titled 'ELECTRONIC DEVICE FOR TRANSMITTING RADIO-FREQUENCY SIGNAL AND METHOD FOR OPERATING SAME
Simplified Explanation
The patent application describes an electronic device that includes various components such as a communication processor, RFIC, power amplifier, and converter. The communication processor is responsible for setting the driving voltage for a specific power amplifier, amplifying an RF signal from the RFIC. This driving voltage is determined based on an APT (Average Power Tracking) mode. Additionally, the communication processor controls the converter to provide the necessary voltage to the power amplifier during the transmission period of the RF signal. Furthermore, during the remaining period when no RF signal is transmitted, the communication processor controls the converter to provide the voltage to the power amplifier based on the occurrence of an event associated with audible noise.
- The electronic device includes a communication processor, RFIC, power amplifier, and converter.
- The communication processor sets the driving voltage for a specific power amplifier based on an APT mode.
- During the transmission period of an RF signal, the communication processor controls the converter to provide the required voltage to the power amplifier.
- During the remaining period with no RF signal, the communication processor controls the converter to provide the voltage to the power amplifier based on the occurrence of an event associated with audible noise.
Potential Applications
- This technology can be applied in various electronic devices that require efficient power amplification and voltage control, such as smartphones, tablets, and wireless communication devices.
Problems Solved
- The technology addresses the need for optimized power amplification and voltage control in electronic devices.
