General Information
Filter is the core product out of RF passive products. Filter is more important than any other passive components in the repeater and the base station, even though other components are important. As the system operators all over the world use different frequencies, and there are quite a lot of signals in the air for televisions, military use, weather research and other purposes. The most important role of the filter is to select desired signals for use. Filter is very the most applied module in RF system. There are lots of filters based on the kinds of applications. When we talk about the concept only, it does not look like hard subject to understand, but 500 pages of a book is not good enough to know about the details and every part of filter. Filter carries out the same function as filter in water purifier which sifts out impurities in water. Filter gets rid of the noise and output the clean signal what I want to get. If you are well aware of S-parameter, you will easily understand the explanation below. As explained above, the filter performs to filter the frequency noise, but at the same time it also can performs to select desired frequency depending on its purpose.
