Hi I am trying to create a equal split Wilkinson Power Divider in puff, but I cannot seem to get the power to split, I have attached the screen shot for two different circuits I built as well as the puff file, any suggestions would be appreciated!
Here is my Puff File:

Copy from the site above and create a .puf file and open it in puff to see the circuit in puff.
Not familiar with that program, but it looks like you are using a symmetrical design (same impedance transmission lines in both channels), but are expecting an un-equal power split? Uhh....the answer is obvious.
Ok, you need to make that resistor "A" be zero ohms, and move the 100 ohm resistor to between the two output ports 2&4 (but placed right after the two transmission lines "B"). Also, make the lead in transmission line from port 1 to the junction be 50 ohm. That should get you close.
Yes. If you put 1 watt in, and split the power in half to two ports, you would expect the power at either of the two output ports to be a little less than 1/2 watt. 1/2 watt + 1/2 watt = 1 watt.
Wow! I haven't seen Puff in a long time. I didn't know it was still around. I learned my first microwave designs using Puff on a MS-DOS computer. The program works well and they would even give you the source code so you could see how they did the programming.
