• Introduction About RF Demodulators
  An RF Demodulator is a type of circuitry which can an RF signal (radio frequency signal) which can be used to decode a signal, usually before it is converted to an audio signal. It is important because the RF signal takes up a lot of bandwidth, but can contain a lot of information. An RF Demodulator can then take this signal and make it easier to decode or it can take the signal and decode it so it is ready to be used in other applications.
• AD8347ARU Application Field and Working Principle
  The AD8347ARU is a type of wideband demodulator designed for use on both the transmit and receive sides in radio communication systems. The chip is designed to operate in the 400 – 15 kHz frequency range. It combines the functions of an RF mixer, oscillator, and demodulator into one integrated circuit.
  The AD8347ARU is designed to work with a variety of different analog and digital modulation formats. It can process both narrow and wideband signals simultaneously. The chip is also highly integrated, allowing for the removal of external components such as mixers, oscillators and external time constant components. This makes it a great solution for applications where space is limited.
  The AD8347ARU consists of multiple sections which work together to recover and process an RF signal. The first section is the RF mixer, which is used to convert the incoming signal into an intermediate frequency (IF) signal. The IF signal is then passed through an oscillator, which is used to adjust the frequency of the signal. Finally, the demodulator section is used to extract the information from the signal. This is done by removing any unwanted noise that may be present, and extracting the baseband signal from the IF signal. The output of the demodulator can then be used for further processing, such as audio reproduction.
• Conclusion
  In conclusion, the AD8347ARU is a highly integrated RF demodulator which is designed to recover a wide range of signals in the 400 – 15 kHz frequency range. It consists of an RF mixer, oscillator, and demodulator sections for processing the signal, making it a great solution for applications where space is limited. With its ability to process both narrow and wideband signals simultaneously, the AD8347ARU makes it an ideal solution for applications which require wideband demodulation.
