Important Aspects of General RF Amplifiers
In the case of a general RF amplifier several key features have to be looked into before making a selection. These features include gain bandwidth linearity and noise figure. Gain means the ampli er’s ability to raise the strength of the signal, while bandwidth means the region of frequency range in which the signal can be amplified successfully. It is also necessary to stress linearity since this causes the amount of distortion that can be within the amplified signal. A small noise figure would help in ensuring that the introduction of disturbances into the system by the amplifier is kept to a bare minimum. In all, these features are quite instrumental in ensuring that the right RF amplifier is chosen for a particular application in order to attain best performance.
