That depends on its purpose. Some examples:
- RF amplifier in IF stage of AM radio: 10KHz.
- RF amplifier in TV set: 6MHz.
- RF amplifier in IF stage of FM radio: 200KHz.
- An RF amplifier in a military RADAR set will probably have very narrow bandwidth to reduce jamming possibility, but wide enough to allow for doppler shift of targets.
What else can I help you with?
Which amplifier has largest bandwidth?
Direct coupled amplifier
What is selective amplifier?
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.
An RF amplifier amplifies the incoming signal by 200 times Calculate the power gain of this amplifier in dB?
If an RF amplifier amplifies the incoming signal by 200 times, the power gain of the amplifier is +25.9 dB. Power is proportional to voltage squared, so the power gain is 400. The decibel scale is 3 times log2 of the power change.
What is the importance of the quality factor Q of a tuned amplifier?
If quality factor is greater then bandwidth will also greater
Need of multistage amplifier?
The Gain provided by the multistage amplifier is greater than the gain of single stage amplifier. The gain of the two stage amplifier is the product of the gain of the individual stages.
rf power amplifier?
rf
What are the Difference Between AF Amplifier and RF Amplifier?
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.
What is a tuned rf jfet amplifier?
It's a junction gate field effect transistor that has it's bandwidth tuned to operate (amplify) in the radio frequency range.
Which amplifier has largest bandwidth?
Direct coupled amplifier
What is the efficiency of class b linear RF AM amplifier?
the approximate efficiency of a class b linear RF AM amplifier is 35%
What are the two types of rf amplifiers?
A unidirectional amplifier & a Bidirectional amplifier
What is a RF amplifier?
A RF amplifier is a device for electrically amplifying the power of an electrical signal, typically, but not exclusively, radio frequency signals.
Is an rf power amplifier useful in the home?
The answer to whether an RF power amplifier is useful for your home depends on the qualifty if your equipment. If your T.V. is getting a weak signal for example, an RF power amplifier may be useful to get a better signal.
What is effect on bandwidth due to positive feedback amplifier?
bandwidth decreases
What is selective amplifier?
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.
What happens when the bandwidth of the amplifier increases?
When the bandwidth of an amplifier increases, it means the amplifier can process a wider range of frequencies. This can result in better signal quality and improved overall performance of the amplifier. However, increasing bandwidth may also lead to increased noise and distortion in the output signal.
RF amplifier of an AM receiver is biased in?
class C
