Review on Wideband Power Amplifier With for Plasma Application

Radio Frequency power amplifiers (RF PA) are widely used for several applications e.g. wireless communication, wireless power transmission (WPT) and radio frequency heating. HF band (3~30MHz) has been widely used in many communication and other systems, in military and civil applications. Generally the circuit design in this band is not a challenge; however this is not the case in some circuits, especially in the case of power amplifier design. The RF devices play a key role in design of power amplifier. In addition, HF frequency is used in many Industrial, Scientific and Medical (ISM) applications. As an example, HF frequency is widely used in plasma generation and heating systems in various applications. LDMOS devices are widely used for power amplifier design and development. Plasma load need to be heated to get desire temperature from RF source. For proper heating of plasma power amplifier plays major role so for plasma application we need highly efficient power amplifier and class-c amplifier offers high efficiency with simple topology, leading to optimal costs of production and system operation therefore this paper gives review for implementation of a high efficiency with high output power of 1.5kw 3-30MHz wideband class-c power amplifier is done for plasma application.
