高性能FEM功率放大模块,FEM功率放大模块,FEM模块,Front-End Module

FEM模块（Front-End Module）是无线通信系统中的关键组件，通过集成多种射频功能用于增强和优化射频信号的发送和接收性能。

G-NiceRF新品PA01F39模块是一款工作频率为400-480MHz的高性能FEM功率放大模块，集成了多项射频功能。该模块内置功率放大器（PA），支持输入功率达30dBm，输出功率可超过39dBm，同时包含低噪声放大电路（LNA）和天线开关。其邮票孔封装设计，小巧紧凑，便于嵌入式集成，大幅降低了用户开发大功率无线模块的难度，简化设计流程，提升开发效率。该模块有IPEX接口和SMA接口，模块适用于无线数据传输大功率放大和无线语音传输大功率放大。

一、模块特点

8V供电，输入30dBm，输出39dBm
内置低噪声放大电路，噪声系数NF=1.0db
工作频率宽，支持400-480MHZ
内置接收发射切换开关，接收和发射只需要一根天线完成
小体积，邮票孔设计，方便客户二次开发

二、模块参数表

三、模块功率输入输出实测

FEM模块本质上是一个信号增强和优化组件，它的功能包括功率放大、低噪声放大、天线切换和滤波，但它不具备信号调制解调和协议处理功能。因此，它需要与模块或芯片配合使用。这里以G-NiceRF全双工对讲模块SA618F30-DZ来测试下，对比下输入输出功率的具体变化。

应用链接图（SA618F30-DZ示例图）

注：以上电流是模块工作在1秒内0.5秒发射，0.5秒接收时的电流，如果是单载波发射，那工作电流要大一倍。

电压与功率对照表（条件：输入功率30dBm，频率：440MHz，50%占空比）

四、关于模块散热说明

此模块是大功率模块，工作时热量非常大，长时间工作必须做好散热，G-NiceRF出货时会标配散热器，用户可以自行选择是否安装，用户可以根据自己的结构做好散热！

下图表格是有标配散热器工作温升数据：

测试温度：28℃ 功率：9W 频率：440MHz

五、模块尺寸（MM）

PA01F39 FEM功率放大模块集成了功率放大、低噪声放大和天线切换功能，支持400-480MHz宽频段，具有小巧的邮票孔封装设计，便于嵌入式应用。模块提供高达39dBm的输出功率，适用于无线数据和语音传输中的大功率放大需求。

模块支持8V供电，同时具备良好的散热性能，满足长时间高功率工作的需求。用户可根据具体应用选择是否安装散热器，以保证设备稳定运行。PA01F39模块是高性能无线通信系统中信号增强的可靠选择。
