In the process of designing a lumped element filter, the circuit layout that is usually used to realize the filter is known as the "ladder network". Why ladder? Simply saying, because the layout looks like a ladder. The picture below shows a ladder network that is consisting of only resistors. In a lumped element lowpass …
Microwave Filter in Satellite Communication
In the previous article, we learnt how microwave filters are used in military around the world in the form of electronic warfare. Today, lets look at how microwave filters are used in satellites. The emergence of satellite technologies in the 1970s has further driven the needs for microwave filters after the increase in importance during …
