Hello all,
What I want to do is make a 50 ohm triax cable to dual coax pigtail. The reason is because the connector for the triax is too big to mount on my PCIe card, and I'd like instead to use two BNC type connectors to bring in the signal, while keeping the signal integrity throughout. I'd like a solution that is completely passive, so I thought about using an EMI shieded box. The triax connection would mount to the box on one end, with the shield connected directly to the box. On the other end, the two BNC connectors would mount, both of their shields are also connected to the box. Inside the box, each center conductor from the triax cable connects to one of the coax conductors. My only concern is the lack of impeadance control once the center conductors are broken out. Also, the triax will be terminated at the box entry.
I know this can be solved with active components, but I do want to keep it passive if possible. Can anyone comment on wether this will work or not?
Tannks!
PS: Details on the triax cable and connector are on the way!
