FIELD: communication devices. SUBSTANCE: device has oscillator, main transmitting circuit, redundant transmitting circuit, control unit, units for analysis of transmitting circuits, testing detectors in power supply circuits, power supply switches, power supplies, two power dividers, three commutators, which use power dividers, power adders, and controlled phase shifters. In addition device has antenna simulators, delay lines, idle load and antenna. When main transmitting circuit fails, control unit switches it of antenna and switches redundant transmitting circuit to antenna without switching of antenna inputs. This is achieved by replacement of high- frequency switches by three commutators, which include power dividers, power adders and controlled full-range phase shifters. They provide possibility to switch arbitrary circuit to antenna input without additional commutation. In addition delay lines are introduced in signal transmitting circuits. They provide delay of transmission of high-frequency oscillations to antenna when units for analysis of transmitting circuits, testing detectors in power supply circuits and control unit operate. This results in possibility to eliminate information losses. EFFECT: increased functional capabilities, increased reliability. |
