Please forward this error screen to 216. Not to wideband amplifier design pdf confused with Audio power amplifier.
Class C VHF power amplifier based on the transistor MRF317. Typically, RF power amplifiers drive the antenna of a transmitter. Some classes are class A, class B, class C and class E.
There is a Class D, but those amplifiers can work only with low frequency signals typically used in audio equipment. Modern RF power amplifiers use solid-state devices such as bipolar junction transistors and MOSFETs. The basic applications of the RF power amplifier include driving to another high power source, driving a transmitting antenna and exciting microwave cavity resonators. Among these applications, driving transmitter antennas is most well known.
Impedance transformations over large bandwidth are difficult to realize, thus most wideband amplifiers use 50 Ω output loading. The loadline method is often used in RF power amplifier design.
