Working Principles

The MAX2440EAI+T is based on a highly integrated architecture that combines the functions of a transmitter, receiver, and associated control circuitry. It operates in the 2.4 GHz to 2.4835 GHz frequency range commonly used for wireless communication. The device utilizes GFSK modulation to transmit and receive data at up to 2 Mbps.

The transceiver integrates a low-noise amplifier (LNA), mixer, voltage-controlled oscillator (VCO), and intermediate frequency (IF) amplifiers. These components work together to amplify and process incoming signals, allowing for reliable data reception. The AGC circuit ensures optimal signal strength by automatically adjusting the gain based on the received signal level.

The MAX2440EAI+T also features a sleep mode that reduces power consumption during idle periods, extending battery life in portable devices.
