Abstract

The influence of continuous microwave fields with the average power level on the characteristics of a square-pulse RC-generator with a multichannel buffer decoupling network and matching circuit is investigated. The RC-generator is made on inverters of the 74HC14 series with a built-in Schmitt trigger. It is shown that increasing the power of the acting electromagnetic radiation reduces the pulse duration and, hence, increases the frequency of the output signal of the RC-generator. Moreover, the sensitivity of the output signal of the RC-generator to the impact of the microwave signal decreases with an increase in either the supply voltage or the microwave signal power. It is stated that the output characteristics of digital radio-electronic systems are the most sensitive to the impact of a microwave signal when using the semiconductor integrated microcircuits as the active elements and when choosing the operation modes of microcircuits by DC voltage, which greatly differs from the rated voltage.
