TYPICAL RF AMPLIFIER CIRCUITS. As a technician, you will see many different rf amplifiers in many different pieces of equipment. The particular circuit configuration used for an rf amplifier will depend upon how that amplifier is used. In the final part of this chapter, you will be shown some typical rf amplifier circuits. Figure 2-19 […]

Video amplifiers , low-frequency compensation for video amplifiers and rf amplifier coupling
VIDEO AMPLIFIERS As you have seen, a transistor amplifier is limited in its Frequency response. You should also remember from chapter 1 that a VIDEO AMPLIFIER should have a frequency response of 10 hertz (10 Hz) to 6 megahertz (6 MHz). The question has probably occurred to you: How is it possible to "extend" the […]

Short circuit protection , summary of filters and answers to questions q1. Through q43.
Short Circuit Protection The main disadvantage of a series regulator is that the pass transistor is in series with the load. If a short develops in the load, a large amount of current will flow in the regulator circuit. The pass transistor can be damaged by this excessive current flow. You could place a fuse […]
