DOM_splitter-50

This 100 ohm balanced power and signal splitter appears to be the same impedance for
communications signals when looking into any port, but produce negligible DC power
loss. The 1V p-p signal (Ch. 1) applied to the common port in the picture below divides evenly.
Half the power appears at each of the side ports (Ch 2 and Ch 3).
The pulse width is typical of the unit baud for DOM high speed communications.
No DC power is being distributed to the side ports in the the picture below.

In the screen snap below, the current of 50 mA injected into the common port of the splitter
divides evenly to each side port. The bias current has some affect on the inductors in the
splitter, causing the signal to sag an additional 2%

Distributing 100 mA (50 mA per side port) results in an additional 4 % sag as seen below.

If the DC path to one side port is interrupted, the impact on the waveform is negligible, as can be seen
by the superimposed traces Ref-1 and Channel 2.

When current is applied to the common port, and a simulated communications signal drives one
of the side ports, a low amplitude triangle pulse appears at the other side port. The origin
of the triangle waveform is not yet completely understood.

No show stoppers so far.
