CHAPTER 1 Components and Systems

Components, those bits and pieces which make up a radio frequency (RF) circuit, seem at times to be taken for granted. A capacitor is, after all, a capacitor—isn’t it? A 1-megohm resistor presents an impedance of at least 1 megohm—doesn’t it? The reactance of an inductor always increases with frequency, right? Well, as we shall see later in this discussion, things aren’t always as they seem. Capacitors at certain frequencies may not be capacitors at all, but may look inductive, while inductors may look like capacitors, and resistors may tend to be a little of both.

In this chapter, we will discuss the properties of resistors, capacitors, and inductors at radio frequencies as they relate to circuit design. But, ...
