When designing an RF or microwave application, you will always need some level of filtering to attenuate or remove unwanted signals from the desired channel. Since the end goal of what a filter must accomplish is quite broad, it may seem daunting to know what qualities to look for in a filter to get there.
At any given time, there are a multitude of signals at a variety of frequencies streaming all around us. This means most RF devices require some level of filtering to attenuate or remove unwanted signals from the desired channel. Without a filter, receiver components can become saturated and unwanted signals can combine with desired signals to corrupt information.
