Advantages and disadvantages of RC coupled amplifier

Advantages:

There are some advantages of RC coupled amplifier which are given below,

• The RC coupled amplifier offers a constant gain over a wide frequency band.
• The circuit is very compact and extremely light.
• It used the resistor and the capacitor which are not expensive so the cost is low.
• The frequency response of RC coupled amplifier is excellent.

Disadvantages:

There are some disadvantages of RC coupled amplifier which are given below,

• The RC coupled amplifier has poor impedance matching because its output impedance is several times larger than the device, at its end terminal.
• It is unsuitable for low frequency application.
• It has low voltage and power gain.
• It has narrow bandwidth.
• It has the tendency to become noisy with times.
