Abstract: PROBLEM TO BE SOLVED: To provide a power supply capable of discharging charges stored in the power supply during testing and maintenance without using large components, and a high-frequency circuit system equipped with the power supply. SOLUTION: This high-frequency circuit system comprises a power supply for individually supplying a predetermined supply voltage to an anode electrode, a cathode electrode, a collector electrode and helix in an electronic tube, an anode switch for turning on or off anode voltage output, and an anode switch control circuit for controlling the anode switch on/off operation so that the pulsed anode voltage can be applied to each of the predetermined cycles repeatedly when operations are stopped in both of a helix power supply and a collector power supply.

Abstract: PROBLEM TO BE SOLVED: To provide a microwave tube system and a microwave tube which can prevent an unnecessary operation stop by suppressing an easy output of an alarm even if discharge is generated in the microwave tube.
SOLUTION: This microwave tube system has a microwave tube in which the same potential is supplied to an anode electrode and a helix and a power supply device which has an excess current detection circuit that detects an excess current flowing into the helix with a time span of a prescribed continuous time or longer causing damage to the helix and outputs an alarm signal, and supplies a prescribed power supply voltage to each electrode of the microwave tube. The microwave tube has a current control element by which connection between the anode electrode and the helix is released and the helix is grounded, and which is connected between the anode electrode and the ground potential and controls the excess current flowing into the helix caused by discharge generated in the microwave tube to a time span shorter than the continuous time in which the alarm signal is not outputted.
