RF signal is coming from an antenna. So it contains electromagnetic waves. But when the signal is processed using electronics circuits, the range of frequency may not be sufficient. So that RF has to be convert to some other frequency acceptable by the circuit. And IF is the intermediate frequency used for tuning & other purpose.

Difference between RF microwave?
RF means radio frequency or relativity low range of frequency microwaves however are into the top range of the spectrum or very hi frequency.
What are the differences between analog and RF circuits?
analog circuit is circuit that generates audio, sound, radio etc (waves of the natural world) RF stand for radio frequency, it is often refer to the property of signal transmission in high frequency (HF). If you say a circuit is RF, the circuit would be in the frequency range between 3kHz to 300GHz. The reason that RF circuit is special is because the performance of signals of higher frequency is different to other lower frequency AC circuits. When designing a RF circuit, RF engineers have to consider the type of wires, lengths, use of components, signal loss etc. It is because high frequency signals would take a piece of wire (longer than 1/10 of signal wavelength) as wires with many inductors and capacitors.
How does frequency modulation work?
Frequency modulation (FM) works by taking a signal, such as an audio signal, and using it to modulate a higher frequency (Radio Frequency, RF) carrier. This modulation causes the RF to shift up and down in frequency. The RF remains relatively constant in amplitude, and its shifting frequency represents the original signal.Contrast this with Amplitude Modulation (AM) where the RF is relatively constant in frequency, but its amplitude represents the original signal.In order to recover the original signal in an FM system, the receiver must demodulate the signal by measuring the time between successive waves of the RF. In a typical broadcast band system, limitations in the the design requirements for tuning the modulated carrier and for demodulating the original signal force the tuning and demodulation to be done in different stages. Using a process known as superhetrodyning, the tuner amplifies the RF with a broad-band amplifier and mixes the RF with a local oscillator (LO) frequency, converting the RF into an intermediate frequency (IF), typically 10.7 MHz. It then passes the still modulated IF (or shifted RF) into a sharp band-pass filter, the IF stage, and removes the interference of other stations from the IF signal. It then demodulates the original signal from the IF signal.Often, the original signal contains encoded information, such as a stereo subcarrier, which is subsequently demodulated and demultiplexed in order to recover the stereo signal. The question, however, asked about frequency modulation, so the answer stops here. If further detail is required, either add it by refining the answer, or comment on the question, and I or someone will refine the answer.
What is the difference between a wave and signal?
1.wave is a three dimensional object where as signal is a two dimensional object
What is rf loop back?
RF Loop Back ,Usually used in all RF Transceivers to covert the Transmitted signal into the Receiver frequency ,checking the Overall performance of the Terminal .This is an Option useful only in maintenance and not recommended BY Standard Authorities (Fcc, ETSI, etc )
The of an antenna depends upon the frequency of the RF signal and the gain?
The size of an antenna depends upon the frequecny of the RF signal and the gain.
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 difference between vga and lcd display?
The main difference between the tow is the signal. VGA uses an analog signal and DVI is a digital signal.
What is the difference between analog and digital transmitter?
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
Is rf signal much more important for capturing or not?
rf is must for modulation and demodulation.
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.
What is the difference between signal processing and signal conditioning?
processing is nothing
What is the difference between signal and wave?
wave is a part of a signal . millions of wave construct a signal .
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 the difference between the modulating signal and the demodulating signal in output of the detector?
Distortion.
Where can one obtain an RF signal generator?
You can obtain a RF signal generator from a variety of locations. You can try your local electronics store. If they do not stock it you can try places such as Amazon or eBay.
