The art of choosing the right balun matching network

Over the years, there have been many attempts to simulate and perfect the balun match. After weeks to months of simulation and trying to understand some level of PCB parasitics, it’s still possible that the match will not work out in your favor when fabricating the PCB design. We suggest starting the design process differently, using the topology shown in Figure 3.

If you’re wondering whether all of this effort and trade-offs are actually worth it, we suggest referring back to Figure 1.
