how to measure or verify the performance of balance to unbalance

Hi all,

I designed a PCB dipole with balun on it, the VSWR is measured well and bandwidth is ok.

I don't know how about the performance of unbalance to balance, anything to measure ? thanks.

You may connect 2 baluns back-to-back and check the perfomance.

But, my balun is designed with dipole on the PCB and can not be measured separately.

You can exactly implement 2 copy of your balun on a seperate PCB and measure them back-to-back
