Imagine the chaos that would arise if my smartphone could pick up any other nearby phone signal. Have you wondered how a smartphone knows which particular signal it needs to communicate with the local cell tower? In addition to multiplexing, your phone and plenty of other RF devices will make judicious use of filtering in order to communicate at the right frequency.

RF devices might seem esoteric, but designing and analyzing critical components for a number of RF devices is not any more difficult than working with other components. With the right analysis package, you can easily simulate an RF bandpass filter and analyze all aspects of your RF filter.

Why RF Filters?

Technically, any type of filter can be used at RF frequencies when the circuit includes the right components. The goal is simply to set the relevant natural frequency and bandwidth to the desired values in order to ensure your filter exhibits the right behavior.
