Baseband chips are even more difficult. The
baseband chip is responsible for handling the core functions of mobile phone communication, such as data decoding,
modulation and demodulation, signal conversion, etc. In contrast, the RF chip is mainly responsible for the transceiver and amplification of wireless
signals, which is relatively simple. Therefore, the design and development of
baseband chip is more difficult, requiring higher technical level and research
investment.
Extension: With the development of mobile communication technology, the functions of baseband chips are becoming more and more complex
, and more frequency bands and communication standards need to be supported, such as 5G, LTE, etc. At the same time, in order to achieve lower power consumption and higher performance, the
process technology used by baseband chips is also constantly upgraded, such as from 40 nm to 14 nm,
7 nm and so on. All these bring greater challenges to the design of baseband chips.
The baseband chip is higher, because the load that the baseband needs to carry is larger, and the second is that the manufacturing process is also more stringent, so it is difficult.
