What is AFE (Analog front-end)?

Radio frequency AFE is utilized in radio receivers, known as an RF front end. An analog front-end is a bunch of analog signal molding circuitry that utilizes delicate analog amplifiers, frequently operational speakers, channels, and application-specific integrated circuits for sensors, radio recipients, and different circuits to give a configurable electronics functional block needed to interface a assortment of sensors to an antenna, analog-to-digital converter, to a microcontroller.
