为什么是的,我有。
由于分离路径,它们非常棘手,并且还因为它们经常需要交叉耦合,这使得时域调整更成问题。
还有一个关于双工器调整的应用笔记,1287-10我认为,或者只是谷歌它,但如果你认真考虑调整双工器,我们创建了一个基于时域方法的过滤器调整程序,它工作得很好
好吧,通过自动化许多测试设置比1287-10简单得多。
你是什么双工器的?
TX和RX BW有多宽,有多少谐振器,更重要的是,TX和RX之间的间距有多宽(如果它小于Tx或Rx BW,则很难处理)。
有交叉耦合吗?
强弱?
(强意味着主耦合的顺序,弱意味着主耦合的1/10或更少)它是可调节的吗?
输入输出耦合怎么样?
它们是固定还是可调节的?
(如果“黄金”或参考滤波器输入耦合与要调谐的滤波器不匹配,则固定会出现问题。即使您不使用,相位调整向导通常也非常有助于设置初始滤波器响应
最终调整的时域调整。

Why yes, I have. They are quite tricky because of the split path, and also because they often require cross-coupling which makes time-domain tuning more problematic.
There is an application note on duplexer tuning as well, 1287-10 I think, or just google it, but if you are serious about trying to tune duplexers, we created a filter-tuning program based on the time-domain method which works pretty well, much simpler than 1287-10 by automating many of the testing setus.
What are you duplexer's like? How wide is the TX and RX BW, how many resonators and more importantly, how wide is the spacing between TX and RX (if it is less than the Tx or Rx BW, it is quite hard to deal with). Is there cross-coupling? Strong or weak? (strong means on the order of the main coupling, weak means 1/10th the main coupling or less) Is it Adjustable? How about input and output coupling? are they fixed or adjustable? (Fixed gives trouble if the "golden" or reference filter input coupling doesn't match the filter to be tuned.
At the very least, the phase tuning wizard is often quite helpful to setup the intial filter response even if you don't use the time-domain tuning for final tuning.
