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 RF amplifier?
A RF amplifier is a device for electrically amplifying the power of an electrical signal, typically, but not exclusively, radio frequency signals.
What is the function of if amplifier in radar receiver?
hahahhahahahaha
What operation Base Transceiver Station perform?
Transmitter section multiplexes baseband signals and modulates it with a carrier,then frequency translates IF to RF by frequency synthesizer and mixer. combines the power to transmit through a antenna before passing it through high power amplifier and bandpass filter. Receiver section passes RF through a band pass filter and low noise amplifier. Downconverts RF to IF by tunable local oscillator and mixer. further the signal is demodulated and demultiplexed before sending to ground communication equipments
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 normally biased in class a class b class c?
class C because Class C also provides better signal,rejects unwanted signal.class c
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 the function of the RF amplifier?
rf is a single tuned amplifier . Its functions are :- 1.improves selectivity ( i.e rejection of unwanted signal) , so that it prevents heterodyning which results in interference frequency. 2. improves image frequency rejection 3. improves sensitivity ( gain of amplifier ) 4.improves coupling of receiver with antenna . 5. improves signal to noise ratio. 6. reradiation of local oscillator through receiver antenna is prevented
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.
Do you connect speakers to receiver or amplifier?
Depends on what your definition of "receiver" is, but most of the time - to the amplifier. Consider: if the receiver is some form of a device that receives some signal, and then decodes it to audio, then the receiver will hook into the amplifier, which in turn will drive the speakers (so the speakers go to the amplifier) if, on the other hand, the receiver is a part of a wireless connection between the amplifier and speaker, then it really serves the role of a cable, so in essence you're again connecting the speakers to an amplifier (only using the receiver as an intermediary) You would have to specify your case.
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.
A class B amplifier is biased?
hi i m nishikantanswer is: in class B devices are biased approx at cutoff.
