Information on RF Amplifier

Typically the RF Amplifier provides gain of the order of 10–30 dB (about 10 to 1,000 times amplification). The RF amplifier must generate as little noise as possible since any noise introduced here further degrades the signal-to-noise ratio. Receivers often have two or more RF stages to produce high sensitivity and low noise, although tracking problems are exacerbated with more than one stage. RF amplification is not utilised in some low-frequency bands since the noise contained in the received signals is so large that a RF Amplifier would adversely affect the signal-to-noise ratio.
