I'm trying to understand how Balun works...
I know it converts a unbalanced
signal to 2 balanced signal...
Also, I wondering if a Balun's operating frequency
is from 800MHz to 1GHz... Will there be attenuation outside the operating frequency?

Hi!
First, a gentle reminder - this thread is "Anecdotes & Gripes" - you
might do better posting this on the "Circuits" or "Antennas" threads...
Second,
a balun converts a signal from unbalanced (2 wires, one "ground", the other "signal")
to balanced (AGAIN, 2 wires - not 2 signals, as a general rule), usually not referenced
to "ground". (Ground is often no more than a convenient fiction at UHF and microwave
frequencies, anyway (Grin!)
Baluns are implemented in a variety of technologies,
some more frequency-sensitive than others. So you can find both narrow-band and wide-band
balun designs. (For the latter, see Jerry Sevick's book "Transmission Line Transformers).
Good Luck! Fred
