Their chip types are different, and their main differences are as follows:
< br >
Different functions: RF chips are mainly used to process RF signals, such as modems and antennas. An SoC, on the other hand, is a complete system-level chip that can contain multiple processors, memory, and other peripherals to implement the functionality of the entire system.
The design purpose is different: RF chips are designed to provide efficient signal processing capabilities in the RF field, while SOCs are designed to achieve functional integrity of the entire system.
Different technical difficulties: RF chips need to have high technical difficulties, including high-precision simulation, low noise, high power and other requirements. The technical difficulty of SoC is relatively low because it needs to support the functional requirements of multiple processors and other peripherals at the same time.
Different application scenarios: RF chips are mainly used in communication and radio fields, while SOCs are widely used in consumer electronics fields such as smartphones and laptops.
