The correct answer is: B. High power
Tuned class C amplifiers are used for RF signals of high power. They are characterized by a high efficiency, which means that they can convert a large amount of the input power into output power. This makes them ideal for applications where power is at a premium, such as in radar and telecommunications systems.
Class C amplifiers are also characterized by a high input impedance and a low output impedance. This makes them well-suited for driving loads that have a high impedance, such as antennas.
However, class C amplifiers also have some drawbacks. They are not very linear, which means that they can introduce distortion into the output signal. Additionally, they can be susceptible to oscillation, which can cause problems with the stability of the system.
Despite these drawbacks, class C amplifiers are a valuable tool for many applications where high power is required.
Here is a brief explanation of each option:
- A. Low power
Tuned class C amplifiers are not typically used for low power applications. This is because they are not very efficient at low power levels. Additionally, they can be susceptible to oscillation, which can cause problems with the stability of the system.
- B. High power
Tuned class C amplifiers are used for high power applications. They are characterized by a high efficiency, which means that they can convert a large amount of the input power into output power. This makes them ideal for applications where power is at a premium, such as in radar and telecommunications systems.
- C. Very high power
Tuned class C amplifiers can be used for very high power applications. However, they are not as efficient at very high power levels as they are at lower power levels. Additionally, they can be more susceptible to oscillation at very high power levels.
- D. None of the above
Tuned class C amplifiers are not typically used for low power or very high power applications. They are most commonly used for high power applications.
