Applications of transformer coupled amplifiers

There are some important applications of transformer coupled amplifier which are given below.

  • The transformer coupled amplifier is commonly used for amplification of RF (radio frequency) signal.
  • It is mostly used for impedance matching between the individual stages.
  • It is used to transfer power to the low impedance load such as loudspeakers.
  • It is widely used as a voltage amplifier in the final stage of multistage amplifier.
  • In order to match the impedance, a step down transformer of proper turn ratio is used.
  • The transformer coupling is generally used when the load is small.
  • It is mostly used for power amplification.
