CHAPTER TWO
Resistors, Capacitors, and Inductors
2.1
INTRODUCTION
At radio frequencies passive circuit elements must be considered more carefully than in lower-frequency designs. The simple resistor, capacitor, or inductor cannot be counted on to provide pure resistance, capacitance, or inductance in high-frequency circuits. Usually the “lumped” element is best modeled as a combination of these pure elements. In addition, when the size of the element becomes larger than 0.1 wavelength in the circuit medium, the equivalent circuit should include the transmission lines.
