关于负载牵引

1982

大家好，我想请教一个问题啊。在ADS里边做负载牵引，能不能在一个圆图上边得到一定带宽内的等功率圆，例如得到5—10GHz的550mw的等功率圆。谢谢大家了

我想应该不能.
只能做某一点负载牵引.

但是在资料上确实看到了，想做一个宽带的功放，但是想来想去牵不出这样的图

You can plot equal-power contours for each frequency, and then try to design matching circuits go through these contours.

However, usually high reflection happens at the output port with power matching. So people usually use balanced structure to get optimum output power and matching simulataneously. [br]<p align=right><font color=red>+3 RD币</font></p>
