Analysis on Application of GaN in 5G Communication Technology

Because of its important strategic position and economic status, 5G communication has become a hot point in information fields. According to its main core technology Massive MIMO(multiple inputs multiple outputs), RF devices which work in it should be smaller and could work in higher frequency and voltage, the traditional material silicon can not continue to serve for 5G communication, GaAs is the main material of 2nd semiconductor and GaN is a kind of new material which is a really good one to fit the request of 5G. Because of the microscope property of GaAs and GaN, they have better performance in communication technology, although silicon is still the mainstream because of its low cost and mature processing, because of merits about bandgap, mobility, and so on, in next ten years, these two better materials will gradually take the place of silicon. This passage will focus on the property of GaAs and GaN and explain how these two materials do benefit to 5th generation communication technology.
