A RF amplifier is a device for electrically amplifying the power of an electrical signal, typically, but not exclusively, radio frequency signals.
class C
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.
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
Yes, but it will be less efficient than one designed for FM.
