Classification of Amplifiers: In the Classification of Amplifiers, the transistor amplifiers may be classified in several ways such as on the basis of transistor configuration used, active device used, output,…
Cryogenically Cooled Amplifiers: The term solid-state is used deliberately here; it does not mean "semiconductor." In terms of the somewhat older maser parlance, it means the opposite of gaseous, i.e.,…
Intermediate Frequency Amplifier: Choice of frequency: The Intermediate Frequency Amplifier (IF) of a receiving system is usually a compromise, since there are reasons why it should be neither low nor…
Transistor RF Amplifier Circuit: A radio receiver always has an RF section, which is a tunable circuit connected to the antenna terminals. It is there to select the wanted frequency…
Tuned Radio Frequency Receiver: The Tuned Radio Frequency Receiver is a simple "logical" receiver. A person with just a little knowledge of communications would probably expect all radio receivers to…
