In the Marchand balun, both RF lines are connected to RF ground. This means you can simply try adding some capacitance or such to enforce this RF ground, and then bias them gether. Added bonus is the fact that the input and outputs are fully isolated, which means whatever you are using to drive your balun can have a DC level on that output. (see picture)
Why 100um and 200um for the Marchand balun ?
Do you guys think if I would be able to simulate a self-drawn marchand balun using software like openems , QucStudio or Z0lver ?
I do not have the money to run ADS on linux.
