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

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
