RFFM4251中文资料2.4 GHz Wi-Fi 前端模块数据手册Qorvo规格书

描述 Description

The RFFM4251 provides a complete integrated solution in a single front end module(FEM) for Wi-Fi 802.11b/g/n/ac and Bluetooth? systems. The small form factor andintegrated matching minimizes layout area in the application and greatly reduces the number of external components.

The module performance is a balance of maximizing on highest linear output power and leading edge throughput while integrating die level filtering for 2nd and 3d harmonics as well as LO spur rejection are included The RFFM4251 integrates a 2 GHz power amplifier(PA), single pole three throw switch (SP3T) and bypassable low noise amplifier(LNA) into a single device.
