BCM4358数据手册RF/IF射频/中频RFID的射频收发器IC规格书PDF

描述 Description

Implements the one- and two-stream 802.11ac specification to enable speeds up to 433 and 867 Mb/s, respectively, and is backward compatible with Not Recommended for New Design 802.11b/g/a/n devices.This product family is used as client devices in smartphones, tablets, set-top boxes, digital televisions, PC products and other products requiring small size and low-power connectivity solutions. Each product has a single-chip dual-band transceiver that integrates all the major functional blocks in a complete 802.11ac wireless subsystem, including radio, baseband and MAC, along with, depending on customer application requirements, Bluetooth and FM radio. These highly integrated solutions provide the increased coverage and throughput performance required for high-quality video and media applications in the home and enterprise and can be added to any end product regardless of the application processor used.
