What are baseband chips, AP and RF chips, and what roles do they play in mobile phones?

First of all, the baseband chip is BasebandProcessor.

Secondly, the application processor is an application chip.

Third, the RF chip is responsible for RF transceiver, frequency synthesis and power amplification.

Fourthly, it plays a role in processing digital signals and radio frequency emission in mobile phones.

AP is the SoC processor of mobile phone, which is used by mobile phone system to run app.

The AP chip is responsible for processing the internal data of the mobile phone, and the system runs on the AP chip.

Baseband is responsible for the realization of the underlying protocol of cellular network, and establishes a port with AP to transmit high-level data.

The baseband processor is responsible for controlling the link layer, organizing data frames and converting them into baseband signals, and then sending them to the RF chip, which modulates the baseband signals to the carrier frequency and transmits them through the power amplifier.

The RF chip receives and sends signals.

The part of a mobile phone that is responsible for communicating with the base station when receiving calls and text messages.
