A radio frequency (RF) amplifier is designed to operate in the RF region which normally refers to
frequencies between 1 MHz to 300 MHz. Great care must be taken in designing an RF amplifier as
most of the components will not portray ideal characteristics at radio frequencies. Most of the RF
Class A amplifiers are tuned amplifiers to obtain higher voltage gain and be less susceptible to noise.
A typical RF Class A tuned amplifier is shown in Figure 3.
