You might want to elaborate a little more. A balun, when properly designed, can perform far better than that.

it's the most simple coax balun, input port's skin is grounding, output port connect two 25Ohm Respectively.

The System impedance is 50 Ohm, two 25ohm is series connected to output port. Is that right, or should be two 50 ohm
series connect. but why? i think when two 25ohm is setted, the circult can be matched.
