Summary

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.

Integrated circuit resistors can be classified into three groups: (1) semiconductor films, (2) deposited metal films, and (3) cermets (a mixture of metal and dielectric materials). Of these, only the first two have found widespread use in high-frequency circuits.

Some of the most important parameters that need consideration in choosing a capacitance are (1) the capacitance value, (2) capacitance value tolerance (3) loss or Q, (4) temperature stability, (5) mechanical packaging and size and (6) parasitic inductance. These criteria are interdependent, so often the appropriate compromises depend on the constraints imposed by the particular application. This chapter considers both hybrid and monolithic capacitor designs.

Inductors operating at radio frequencies have a variety of practical limitations that require special attention. Design, resistance losses, and monolithic spiral inductors are discussed
