Default RF power splitter design (was something else)

Okay, I couldn't figure out what operational use it would have.


Actually, I've noticed that on checking up the mini circuits pointers
that the splitters they manufacture are only good for a given
frequency range. And I don't mean DC- Fx; I mean from say 30Mhz -
1000Mhz or similar. I'd have thought this type of stuff would have a
bottom end of *DC* not some relatively high radio frequency. We're
only talking about power splitters after all, not broadband filters.
So why the low frequency cut-off? Are there some capacitantances
utilized in these designs and if so, what are they doing there?
