Lumped and Distributed Circuits

RF components are frequently made up of several different electrical components called discrete components. For instance, while an RF amplifier is an RF component, it is made up of several discrete electrical components like diodes, transistors, and the big three: resistors, capacitors, and inductors. Resistors, capacitors, and inductors are small, inexpensive passive electrical components used to shape electrical signals and are utilized in some combination in every electrical circuit.

When electrical components are combined together in a defined area to perform some prescribed function, the components are said to form a circuit. In the world of RF, there are two philosophies behind circuit ...
