Description

technical field [0001] The invention relates to a test compensation device and a method thereof, in particular to a power sensor frequency characteristic test compensation device and a method thereof for a high-power transmitter. Background technique [0002] The detection of the output power of a high-power transmitter is very important to the normal operation and protection of the transmitter. Usually, a directional coupler or a voltage divider is connected to the output of the transmitter to take out a suitable high-frequency output signal, which is converted into a DC voltage signal by a detection diode after a compensation network, and then sent to an indicating circuit or a microprocessor for processing. Before entering practical use, the detection diode and its compensation circuit must be debugged and calibrated for indication accuracy and frequency response. This usually needs to be done on the whole machine. First connect the transmitter to a dummy load of corres...

AI Technical Summary

Problems solved by technology

Due to the inconsistency of the detection frequency characteristics of diodes, this kind of compensation network cannot be designed as a circuit with uniform parameters. It can only be prepared by power-on and debugging, and it needs to be debugged and measured one by one, including replacing resistors, capacitors, and even detection. diode

It is conceivable that the debugging time is long and the power consumption is large, and rich debugging experience is required

However, the existing diode standards do not have indicators related to the detection frequency characteristics, and there is no method and device for testing the detection frequency characteristics of diodes.

[0004] As high-power transmitters have higher and higher requirements for power sensor detection accuracy and DC detection frequency characteristics, the existing design and debugging technology has been difficult to meet the needs of product production and debugging
