移相电路如何设计

老大，你问的是电调天线?移相器可是比较难的东东哦，原理很简单，一般都是通过滑动接触点来实现，做起来比较难哦

我们公司做过分段的数控移相器，但是连续的不知道怎么实现 ?

我们用电桥和变容二极管实现，不晓得是不是小编需要的

回楼上：需要
电桥和变容二极管实现的移相器，可承受多大功率

应该很小吧，小编用来做什么的?

功率合成时，想调节每个功放单元的相位

前馈?

先调相后功放

电桥和变容管承受功率应该不小了一般的功放应该行

做线性功放的?

顶一下

使用压控变容器件吧，窄带的比宽带的好做。

for your situation, I do not suggest you to design such phase shifter. the simplest method of tuning phase in high power situation is to add tuning tab manually. certainly drawback is the output matching will be destroyed. I guess your boss want to tune for power when several PA combined together. I have such experience too. But really difficult and troublesome.
the suggestion is to tune phase at the input when signal is small (< 30dBm). if you or your boss persist on the idea, try the following:

It is expensive (>$2000/PCS)
