Features of the Application of Protective Devices in 5G Technology

Abstract

The principle of construction of wide-band self-controlled power limiters mm - wavelength range is proposed in the work. The operating range, which includes the 28 GHz and 38 GHz frequency range used by 5G technology, is considered. Losses of the limiter in the small signal mode in this range do not exceed 2 dB. At the same time, the attenuation in the high-power input signal mode is about 30 dB in the entire range of operating frequencies. Methods of calculating the characteristics of self-controlled power limiters are provided. Ways to optimize their design are considered. A similar construction of the limiter can be used in the 60 GHz frequency range, which is also used by 5G technology.
