The BCM4398 from Broadcom is a Wi-Fi 7 and Bluetooth 5.2 Combo Chipset that operates from 5 to 7 GHz. This low-power, highly integrated Wi-Fi 7 and Bluetooth 5.2 combo chip is optimized for mobile handset applications where high performance, low latency, low power consumption, and small solution size are key requirements. It has channel bandwidths of 20/40/80/160/320 MHz for 2x2 5 GHz and 6 GHz radios and 20 MHz channels for the 2x2 2.4 GHz radios.
This chipset contains a simultaneous dual-band (SDB) 2x2 IEEE 802.11be-compliant radio, a dual-core Bluetooth (BT) 5.2 radio, and a dedicated scan core that enhances Bluetooth and WLAN system operation. It supports data rates of up to 6 Gbps and a 4K-QAM modulation scheme. The chip also has full legacy compatibility with IEEE 80.11a/b/g/n/ac/ax. It has a PCIe Gen3 interface and is ideal for low-power mobile devices and AR/VR applications.
