REDUNDANT DEVICE Russian patent published in 1994 - IPC

FIELD: transmitting devices of long-range radars. SUBSTANCE: device has main and redundant units which are connected through switching unit with power supply wires, and control signal source. Main and redundant units are made of reflection oscillators. Switching unit has double button which is connected to thyristor and power supply circuit of focusing coil of reflection oscillator of main unit. Thyristor cathode is connected to input of introduced second triac. In addition threshold gates and differentiating circuits as well as transformer, decoupling diodes and inverters are introduced. EFFECT: increased functional capabilities. 2 dwg
