The term "baseband chip" refers to an integrated circuit that handles the basic functions of transmitting and receiving signals within a communication system. Some synonyms for this term include "modem chip," "transceiver chip," and "signal processing chip." These chips can be found in a wide variety of devices, including smartphones, tablets, and other wireless communication devices. They are responsible for converting digital data into analogue signals that can be transmitted over a radio frequency channel, and vice versa. As technology continues to evolve, so too do the functions and capabilities of baseband chips, ensuring that they remain an essential component of modern communication systems.
