[SOLVED] splitter performance down to dc

[Kooky613]

I am thinking to use this splitter from macom MAPD-010638-C2WSOT (5-1600MHz)

Can anyone predict the performance of this component down to dc and explain what will happen?

I am interested down to 50khz (not dc)..

It is difficult to predict but I would imagine the slope of the isolation and insertion loss graphs would continue in the same direction. I don't think it would work at all at DC so somewhere between DC and 5MHz it will simply cease to work. For low frequencies you would probably be better to use a simple resistive divider.

You can compare with the data provided by MiniRF for a similar splitter (5-1600MHz), but for which, the manufacturer provides information below the minimum published frequency.
