Hi Guys, I'm designing a Wilkinson power splitter to work around 160 MHz using lumped element components. I've designed the splitter as per the standard design procedure for a series L / shunt C topology (values are 13pF, 27pF, 68nH) and it works well. However I need to add some high pass filtering to my circuit and I'm wondering can I design a high pass version of the wilkinson splitter (instead of the standard low pass version) to combine the two functions? I've added some high pass filtering in before the splitter but my in-band insertion loss becomes too high.

Does anyone know where would I find how to do the calcs for this, if it's possible?

Many thanks,
Dave
