Just a hint -- these are exactly 11667A at a cheaper price:
Methinks it was RLC Electronics who made those 11667A splitters for
HP/Agilent. They also made that 1.9GHz low pass filter used for 8753x
adjustments.
Just make sure to test them when received -- I purchased two and one of them
had one resistor open. The seller shipped a replacement immediately once the
problem was reported to him. Don't know if it is good yet -- it is still
enroute...
Datasheet is e.g. here:
Here is the RLC Catalog with good data:
139 pages.
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!
