Gallium is used to make the compounds gallium arsenide (GaAs) and gallium nitride (GaN) which are used to manufacture these devices. Other applications of gallium include low-melting metal alloys, mirrors, and medical thermometers. How was it discovered? Gallium was first predicted by Russian chemist Dmitri Mendeleev. This paper presents a novel multi-channel type RF source module with solid-state power amplifiers for plasma generators. The proposed module is consisted of a DC control part, RF source generation part, and power amplification part. A 2-stage power amplifier (PA) is combined with a gallium arsenide hetero bipolar transistor (GaAs HBT) as a drive PA and a gallium nitride high electron mobility
