Microwave frequency-mixing loopback detection device

Abstract

The invention discloses a microwave frequency-mixing loopback detection device which comprises a circulator, a first coupling circuit, a frequency mixer, a second coupling circuit, a clock generation unit and a power supply module unit, wherein the circulator, the first coupling circuit, the frequency mixer and the second coupling circuit are sequentially connected for forming a loop, the power supply module unit is connected with the clock generation unit, and the output end of the clock generation unit is connected with the input end of the frequency mixer. The microwave frequency-mixing loopback detection device is used for detecting the running situation of a 5.8GHz microwave device of an end station, has simple operation, lightweight and compact design and convenient carrying, and can independently check the running situation of the microwave device of the end station under the situation of being unnecessary to be matched with the end station, thereby having broad application prospects in the aspects of debugging, detection, maintenance and the like of microwave communication circuits.

Description

technical field [0001] The invention relates to a detection device for a microwave communication line, in particular to a microwave mixing loop detection device for detecting the operation status of microwave equipment in a local end station. Background technique [0002] Microwave communication is an important means of communication in China's communication network because of its wide frequency band, large capacity, good quality and can be transmitted to a long distance. It is also generally applicable to various special communication networks. Microwave communication has good disaster resistance performance. , for natural disasters such as floods, wind disasters and earthquakes, microwave communication is generally not affected, and has been widely used in the transmission of various telecommunication services, such as telephone, telegraph, data, fax and color TV. [0003] There are many types and models of microwave equipment used in microwave communication, the circuit s...

Problems solved by technology

The digital oscilloscope spectrum analyzer with the above-mentioned structure is expensive, bulky, and heavy, and it is difficult to equip a large number of grassroots units. It needs AC power supply, the operation process is complicated, and it is not easy to operate at high places. On a steel tower tens of meters high, when a fault occurs, due to the lack of microwave signal detection equipment, it is difficult for grassroots microwave station personnel to determine whether it is the local end or the opposite end equipment fault and the faulty unit, which will cause further maintenance and detection work. very difficult
