The microwave power amplifier tube that microwave power amplifier uses, due to semiconductor own characteristic, having higher quiescent current, namely also having higher power consumption when not carrying out power amplification to microwave signal.Microwave power amplifier tube only amplifies input signal, and output signal can change along with the change of input signal, and this just needs an output power.In the unmatched situation of load, the signal reflex of output is on microwave power amplifier tube, and long-time reflection can make the microwave power amplifier tube life-span decline, and even may cause the damage of microwave power amplifier.As can be seen here, accurate output control technology and good load matching technique have very important effect to microwave power amplifier.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of microwave power amplifier, can carry out power supply control to microwave power amplifier tube.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of microwave power amplifier, comprise the first coupler, first detector, microwave power amplifier tube, circulator, second coupler, second detector, load, processor, electric power bias circuit and controlled switch, microwave signal is input to the input of described first coupler from microwave input port, the output of described first coupler connects the input of described microwave power amplifier tube, the output of described microwave power amplifier tube exports the microwave signal after amplifying to described circulator, one end of described circulator is as microwave output port, the other end of described circulator connects the input of described second coupler, the output of described second coupler connects described load, the coupled end of described first coupler connects the input of described first detector, the output of described first detector connects described processor, the coupled end of described second coupler connects the input of described second detector, the output of described second detector connects described processor, power supply is input to described electric power bias circuit from power interface, described electric power bias circuit is powered to described processor and by described controlled switch to described microwave power amplifier tube, the controlled end of described controlled switch connects described processor, wherein, the rectified signal of described processor to described first detector and described second detector compares, and when the difference between described first detector and the rectified signal of described second detector exceedes predetermined threshold value, controls described controlled switch and disconnects.
