Abstract
PURPOSE: To stop the power supply to stop the booster automatically and to the operation, if the booster amplifying the signal at antenna system causes oscillation.
CONSTITUTION: If the booster 1 causes abnormal oscillation, the output voltage is picked up from the signal branching circuit, it is detected with the diode 12 and is smoothed with the capacitor 20, and is fed to the transistor 13 of the failed voltage detection circuit being a DC amplifier. The abnormal oscillation voltage is amplified with the transistor 13 and becomes the control signal to the transistor 14. When the transistor 14 is conductive, the current interrupter 15 is operated and the supply of power to the booster 1 is topped
