Overview of Baseband Chips

🟠A baseband chip is an important device that connects the central processing unit (CPU) and the radio frequency (RF) chip, responsible for processing information. After processing by the CPU, the information is modulated into a digital signal by the baseband chip, then transmitted through the RF chip, and finally emitted by the antenna. The signals … Read more
