Additional Details

The SKY77491-15B module is designed to meet the stringent requirements of GSM/GPRS/EDGE systems. It incorporates a high-efficiency power amplifier to maximize battery life and minimize heat dissipation. Integrated harmonic filters ensure compliance with regulatory requirements for spurious emissions. The integrated antenna switch allows for seamless switching between transmit and receive modes. The module operates across the GSM/GPRS/EDGE quad bands (850, 900, 1800, and 1900 MHz), making it suitable for global deployment. The small form factor of the module further contributes to reducing the overall size and weight of mobile devices. This FEM is controlled using low voltage signals, aiding in power conservation and interfacing simply with baseband processors.
