EHF power limiter intended for protection of the low noise amplifiers from the impact of video-pulses of nanosecond duration

The EHF protective device with different polarity wiring scheme of limiting p-i-n-diodes intended for protection of low noise amplifiers within the range of frequencies 0.1...4.0 GHz from the impact of unit pulses of nanosecond duration were developed. Frequency descriptions of the insertion loss and coefficient of voltage standing wave at reception conditions of designed EHF power limiter were investigated. It was shown that using of the designed protective device in composition with the low noise amplifiers does not depress the sensitivity of radio receiver on the whole. Experimental data of the hardness of designed EHF protective device under the impact of unit video-pulses of nanosecond duration were given. High functioning effectiveness of the protective device with different polarity wiring scheme of limiting p-i-n-diodes at wide amplitude range of video-pulse voltage was shown.
