ELECTRONIC DEVICE AND HARMONIC CONTROL METHOD OF ELECTRONIC DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18477782 titled 'ELECTRONIC DEVICE AND HARMONIC CONTROL METHOD OF ELECTRONIC DEVICE

Simplified Explanation

An electronic device described in the patent application includes a processor, memory, a power management integrated circuit (PMIC), a radio frequency integrated circuit (RFIC), a power supply module, a front-end module, a variable notch filter, and an antenna. The processor controls the PMIC and power supply module to supply power to the front-end module and controls wireless communication operations using multiple frequency bands. Based on the wireless communication operation, the processor adjusts the impedance of the variable notch filter to remove a harmonic frequency.

  • The electronic device includes a processor, memory, PMIC, RFIC, power supply module, front-end module, variable notch filter, and antenna.
  • The processor controls the power supply to the front-end module and performs wireless communication operations using multiple frequency bands.
  • The processor adjusts the variable notch filter's impedance to remove a harmonic frequency based on the wireless communication operation.
  • The device enables modulation and amplification of RF signals received from the RFIC.
  • The variable notch filter is connected to the power supply module and front-end module, removing a harmonic frequency from the transmission signal.
  • The antenna is connected to the front-end module for wireless communication.

Potential applications of this technology:

  • Wireless communication devices such as smartphones, tablets, and IoT devices.
  • Radio and television broadcasting equipment.
  • Radar systems and satellite communication devices.
  • Wireless networking equipment and routers.

Problems solved by this technology:

  • Removes unwanted harmonic frequencies from the transmission signal, improving signal quality.
