求教ADS中的三端口的S参数文件怎么导入到ADS中呢？

向各位求教一下
我查了一些混频器的器件，是hittite公司的，我下了DATA SHEET和它提供的S参数文件，我看不懂它提供的S参数文件，帮我看看，行吗?怎么使用公司给的S参数文件，下面显示的图片就是厂家给的S参数文件，是一个压缩包，打开包含下面的文件：
HMC141 RF Return Loss with LO=12GHz @ 17dBm deembedded.s1p
HMC141 RF Return Loss with LO=12GHz @ 15dBm deembedded.s1p
HMC141 RF Return Loss with LO=12GHz @ 13dBm deembedded.s1p
HMC141 RF Return Loss with LO=12GHz @ 10dBm deembedded.s1p
HMC141 LO Return Loss with 17dBm deembedded.s1p
HMC141 LO Return Loss with 17 dBm deembedded.s1p
HMC141 LO Return Loss with 15dBm deembedded.s1p
HMC141 LO Return Loss with 13dBm deembedded.s1p
HMC141 LO Return Loss with 10dBm deembedded.s1p
HMC141 IF Return Loss with LO=12GHz @ 17dBm deembedded.s1p
HMC141 IF Return Loss with LO=12GHz @ 13dBm deembedded.s1p
HMC141 IF Return Loss with LO=12GHz @ 10dBm deembedded.s1p
这是该器件S参数文件压缩包里的所有文件，我全部弄出来了，混频器都是三端口的器件，这里都是给出来的s1p文件，怎么选择相应的文件并导入ADS中呢，请遇到这种情况的网友给指教一下吧！
我打开了一个其中的一个HMC141 RF Return Loss with LO=12GHz @ 17dBm deembedded.s1p文件，里面显示的是：
