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.
