MediaTek MT6639 Datasheet

The MediaTek MT6639 is a highly integrated single chip with a low-power 2x2 2.4GHz and 2x2 5/6GHz DBDC 11a/b/g/n/ac/ax/be Wi-Fi subsystem and Bluetooth v5.3 subsystem, providing a high standard of feature-rich wireless connectivity and delivering reliable, cost-effective long-range throughput. The optimized RF architecture and baseband algorithm provide superior performance and low power consumption. The Smart MAC design deploys an efficient offload engine and hardware data processing accelerator that completely offloads the host processor's Wi-Fi tasks. The MT6639 is designed to support standards-based features in the areas of security, quality of service, and international regulations to provide the best performance for the end user at all times and in any situation. features The MT6639 is a 2-in-1 connectivity chip that includes two 2.4 GHz Wi-Fi transceiver front ends, two 5 GHz or 6 GHz Wi-Fi transceiver front ends, and a Bluetooth transceiver front end in a single package.
