Microwave mixing loopback detection device

Abstract

The invention discloses a microwave mixing loopback detection device which comprises a circulator, a first coupling circuit, a mixer, a second coupling circuit, a clock generation unit and a power module unit, wherein the circulator, the first coupling circuit, the mixer and the second coupling circuit are connected in sequence to form a loop; the power module unit is connected with the clock generation unit; the output end of the clock generation unit is connected with the input end of the mixer. The microwave mixing loopback detection device provided by the invention is used for detecting the operating condition of 5.8GHz microwave equipment at the home terminal station, is simple to operate, light, small and exquisite in design and convenient to carry, can be used for independently detecting the operating condition of the microwave equipment at the home terminal station without the coordination of the opposite terminal station, and has wide application prospect in the aspects of debugging, detection and maintenance 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 not affected at all, 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 stru...

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
