Quanxun technology is a high-tech company for R & D and manufacturing of wireless communication components. It was established in 1999 to develop and produce microwave components such as microwave (power) amplifiers and low noise amplifiers. (RF microwave (power) amplifiers and low noise amplifiers play a key role in the whole wireless communication system. Their output power determines the length of communication distance, and the power efficiency determines the power consumption and use time.)
