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.
Tell you what an intermediate frequency amplifier do?
The intermediate frequency (IF) amplifier lies between the mixer and the demodulator. The mixer shifts the input radio frequency (RF) signal into the range of the IF amplifier. The IF amplifer is a band pass amplifier, so only RF signals that are the IF frequency distance away from the local oscillator in the mixer can pass through to the demodulator. This process is called the superhetrodyne process.
RF amplifier of an AM receiver is biased in?
class C
How do you calculate gain of an inverting and non-inverting OP-Amp configuration?
gain in an op-amp is the output voltage divided by input voltage. for the inverting amplifier , gain(Av)=-(Rf/Ri) ,where Rf => resistance of the feedback path & Ri=> inverting input terminal resistance for the non-inverting amplifier , gain(Av)=(1+(Rf/Ri)) , where Rf => same & Ri=> non inverting input terminal resisance
Can an am rf amplifier at 27 mhz work on FM at same frequency?
Yes, but it will be less efficient than one designed for FM.
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 selective amplifier?
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.

RF amplifier of an AM receiver is biased in?
class C
What is Bandwidth of RF amplifier?
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 is the difference between a RF cord and AV cord?
An RF cord plugs in the back of a tv and a AV plugs in the yellow in white oulet and RF cords are SNES and NES!!!!!!!!!!!!!!!!
What difference between RF power output watt and electrical power output watt?
The difference is in the output 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 data transmission speed is needed for one voice channel?
09. A tuned RF amplifier is
