I'm currently in the process of building my own DIY 11667A power splitter as the cost of these things from Keysight is insane, and even second hand is rather too expensive.
I can only test this one to 3.2GHz as that's the limit of my VNA (Siglent SVA1032X) but that's all I need for now which makes things a bit easier.
I plan to use two 100ohm SMD resistors in parallel, oriented back to back so the resistive side of the resistors are together to hopefully reduce parasitics a bit.

I have my diecast box with 3x N-connectors, but I'm wondering if the resistor placement in the box will have an effect on performance?

For example, these 4 basic connection ideas:



Are any of these (or even something different) better than the others to save me running through all permutations, or does it not matter?


Thanks!
