Bandwidth is just the range of frequencies. For example, currently I'm building an audio equalizer and the bandpass for a specific filter may have a bandwidth of 1 to 3 kHz or something like that. Here is a link to Wikipedia to explain what a LNB does. From glancing at the article, it looks as though it includes some specific I.C.'s and more, so good luck.
