FIELD: electrical engineering.SUBSTANCE: sensitive element for registration of UHF band signals represents a four-pole containing two pairs of in-series metal-semiconductor and semiconductor-metal junctions, the semiconductor representing a conductive channel common for the both said pairs. The first pair of junctions, being Schottky junctions, has two metal outputs designed in the form of metal layers hat are connected to the UHF circuit while the two pairs of outputs of the second pair, designed in the form of metal layers, are connected to the LF circuit for measurement of the conductive channel impedance, currents caused by the registered UHF signal present in part of the channel.EFFECT: creation of a device enabling increased sensitivity of reception at high frequencies of the signal to be measured and simplification of the sensitive element fabrication technology.7 cl, 5 dwg |
