Lumped components such as resistors, capacitors, and inductors make up most of the glue that allows microwave discrete transistors and integrated circuits to work. Lumped components provide impedance matching, attenuation, filtering, DC bypassing, and DC blocking. More advanced lumped components such as chokes, baluns, directional couplers, resonators, and EMI filters are a regular part of RF and microwave circuitry. Figure 6.1 shows examples of lumped resistors, capacitors, inductors, baluns, and directional couplers. Surface mount techniques and ever-shrinking package sizes now allow solderable lumped components useful to 10 GHz.
