A RADIO-FREQUENCY (RF) AMPLIFIER uses FREQUENCY-DETERMINING NETWORKS
to provide the required response at a given frequency.
The FREQUENCY-DETERMINING NETWORK in an rf amplifier provides maximum
impedance at the desired frequency. It is a parallel LC circuit which is called a TUNED CIRCUIT.
TRANSFORMER COUPLING is the most common form of coupling in rf amplifiers. This
coupling is accomplished by the use of rf transformers as part of the frequency-determining network for
the amplifier.
