HG FA431 applied in aerial refueling

In 1988, according to the Chinese Ministry of electronics industry task arrangement, our company technical director Wang Daoxiu, successfully developed the working frequency of 225M, 10W, 28V high frequency transistor FA431. This device was successfully developed and applied.

Based on FA431 technology, we developed 400M serie transistor (TV transmitter), 225M serie transistor (FM radio).
