Second, the technical principle of low delay communication UWB RF chip
Low delay communication UWB RF chip is the key component of UWB communication, its technical principle mainly includes signal generation, modulation and demodulation, signal amplification and filtering and so on.
Signal generation
The UWB RF chip generates short pulse signals through the internal high-precision clock and pulse generator. These pulse signals have a high time resolution, which can ensure the fast transmission of information and accurate positioning.
Modulation and demodulation
In order to load the information to the pulse signal effectively, the UWB RF chip adopts a specific modulation mode, such as pulse position modulation (PPM), pulse amplitude modulation (PAM) and so on. At the receiving end, the RF chip extracts the information from the pulse signal through the corresponding demodulation mode.
Signal amplification and filtering
Because the UWB signal will be subjected to various interference and attenuation during transmission, the RF chip needs to have high signal amplification capability and filtering performance. By using advanced low noise amplifier and filter technology, the receiving sensitivity and anti-interference ability of the signal can be effectively improved.
