I need the formula to calculate percent of bandwidth,
as in "60 GHz, +/-5%." Can someone help?

Hi jstover,
If we assume that there is a
given center frequency called fc and we need to
know the ranges we need to measure around fc in
percentage, we can use the following formula to
find the lower(fl) and higher(fh) frequencies which
the percentage will allow.
fl=fc*(1-%/100)
fh=fc*(1-%/100)
So, if we assume that
fc=60GHz and there is a +/- 5% bandwidth around
this, then we can find:
fl=60GHz*(1-5/100)=57GHz
fh=60GHz*(1+5/100)=63GHz
I hope this
is what you were asking for and that it helps you
out.
-J

Thanks for your response. Somehow, I remembered
it as being more complex than simple percentage
math.
