Abstract
An amplifying apparatus is provided, which includes a power-source main line, a plurality of amplifying control devices which include an amplifier, a power-source branch line, an over current protector. The amplifier amplifies a high-frequency signal. The power-source branch line is branched from the power-source main line. The over current protector disposed for the power-source branch line is connected to the amplifier and configured to disconnect the power-source branch line based on drive current flowing through the amplifier from the power-source branch line. The power-source main line is common to the plurality of amplifying control devices.
Claims18
An amplifying apparatus, comprising:
- a power-source main line;
- and
- a plurality of amplifying control devices comprising:
- an amplifier configured to amplify a high-frequency signal;
- a power-source branch line, branched from the power-source main line;
- an over current protector disposed for the power-source branch line connected to the amplifier and configured to disconnect the power-source branch line based on drive current flowing through the amplifier from the power-source branch line;
- monitoring circuitry configured to generate a monitoring signal based on a change in the drive current or a change in a drive voltage corresponding to the drive current;
- and
- a failure count detector configured to output a failure count detection signal indicative of a number of failures that is a number of power-source branch lines disconnected by the over current protector, based on a signal intensity of the monitoring signal,
- wherein the power-source main line is common to the plurality of amplifying control devices.
