COFDM高清数字无线图传开发套件
COFDM高清数字无线图传开发套件采用COFDM调制技术，完整实现了高清数字无线图传功能，供用户学习、评估和测试COFDM图传技术。该开发套件包括发射端和接收端两部分。发射端通过HDMI接口输入数字视频信号，经H.264编码压缩后做COFDM调制(实现基带功能)，再经DAC转换成模拟信号给RF Transmitter后通过PA(功率放大器) 放大信号至天线发射出去。Sihid COFDM无线图传开发套件发射端包括SEM9363编码调制板和D-PA2400A功率放大板两块电路板。接收端包括FC2400A下变频板和COFDM Demodulator模块，通过USB接口将解调后的数字视频信号传给手机(或PC、平板)做H.264解压播放。

SEM9363编码调制板(B版本)：
Sihid SEM9363无线数字图传编码调制板通过HDMI接口输入高清数字视频到Hi3516A处理器做H.264压缩编码，压缩后的视频信号通过FPGA实现COFDM信道调制，再经AD936x转换为模拟信号调制发射出去。为方便用户使用，SEM9363板B版本将Hi3516A调试串口、FPGA JTAG调试口、OSD接口、控制串口、电源等信号集中到J30传到D-PA2400A板的对外接口上。
D-PA2400A功率放大板：
D-PA2400A功率放大板包含两路独立的射频功率放大模块，将SEM9363A输出的射频信号进行功率放大输出。D-PA2400A板的J3接口与SEM9363板(B版本)的J30接口相连，将SEM9363板上的Hi3516A调试串口、FPGA JTAG调试口、OSD接口、控制串口、电源等信号集中到D-PA2400A的板边对外接口上。SEM9363板的两个RF输出分别通过IPEX连接线接到D-PA2400A板的两个RF输入接口。D-PA2400A板上的每路功率放大模块工作指标：
