Hi Chris,

If this relates in some way to your published return loss
characteristic, then I have to offer that it is hardly representative
of the best of BalUns to offer. Sevick offers at least half a dozen
with scads less loss and operating flat to within less than a fraction
of a dB.

Now by your tying in an implicit BW from 600KHz to 500MHz, this comes
too close to brightening your teeth and improving your sex life.
Within 3dB? Given your design, and it being voltage based, supporting
flux through currents driving the core, 3dB would be a hell of a dummy
load and hardly a crowning achievement.
