Hi
I am designing a wideband low noise amplifier in the W band range(75 -110 GHz). I read few research papers and I then chose one which made sense to me.
Now i am trying to implement it step by step what they tried to do in it. I am attaching my schematic and the schematic in the research paper here. As you can see that they used 0 ohm transmission lines for AC grounding. I read a lot about them on the internet but i didn't understand how 0 ohm transmission lines are being used here for separating the AC and the DC parts. Can you please guide me what I am doing wrong here and how should i move forward.
0 ohm transmission lines are the one with two white lines with black line in the middle. I have highlighted the passage in the 3rd image where it is explained what those lines are doing here.
I am waiting for some helpful replies. Thank you
