嗨,我是ADS的新用户,只知道基础知识;我必须创建一个具有8个混频器的电路,并将其IF基带信号上变频为8个频率,并使用两个4x1分路器将结果信号组合在同一条线路上,该分路器与一个2x1分路器相结合;已经使用来自minicircuits.com的下载数据的数据项获得了分离器。 (我附上了一些图像以显示原理图设计)我一直在模拟结构,直到它有6个频率和任何分离器工作。它还使用4个频率和两个分离器。问题来自于我试图用分路器模拟8个信号(后来,我还想添加放大器和噪声模拟):它以“异常模拟终止”结束;显示的原因通常是“内存不足”或“没有收敛”(我尝试将求解器更改为Krylov,降低8个基频的顺序,尝试使用瞬态求解器辅助)。我的内存是4GB,我的处理器是intel centrino 2;我在具有26GB可用空间的windows7 32位操作系统上使用ADS 2009(我需要32位系统才能看到布局)。事情应该足够了。有什么东西我不见了吗?

It also worked with 4 frequencies with two splitters. The problem came when I tried to simulate the 8 signals togheter with the splitters (later, I will also want to add an amplifier and noise simulation): it ends with "abnormal simulation terminated"; the reasons displayed were typically "insufficient memory" or "no convergence" (I have tried changing solver to Krylov, decreasing the order of the 8 fundamental frequencies, trying to use transient solver assisting).My ram is 4GB, and my processor is intel centrino 2; I use ADS 2009 on a windows7 32bit operating system with 26GB free space (I need 32 bit system to be able to see the layout). Things should be enough. Is there something that I'm missing?附件AMixer.jpg205.0 KBBMixerswithcombiners.jpg56.8 KBCHBsettingswithsimulation.jpg281.0 KB
