Abstract
The utility model relates to a kind of Microwave Measurement And Adjustment aid.Comprise probe, radio-frequency cable, connector and load; One end of radio-frequency cable is connected to probe, and the other end is connected to the welding end of connector, and described connector thread end is connected to load.Radio-frequency cable is the flexible cable with metal screen layer, and pop one's head in as the copper inner wire of radio-frequency cable, connector is microwave radio signal connector, and load is the load of microwave radio power absorption.The utility model adopts the signal absorption principle of microwave circuit, does not namely use the step of dismounting, welding, realizes the localization of fault work that multichannel microwave distributes combiner circuit.Avoid conventional fault detection and location repeated disassembled and assembled to a certain extent, weld the loss that device is reprocessed and microstrip circuit is scrapped that causes, improve the efficiency that Microwave Measurement And Adjustment and fault are reprocessed.This Microwave Measurement And Adjustment aid has that structure is simple, with low cost, easy and simple to handle, high, the portable advantage of localizing faults efficiency.
Description
Technical field
The utility model belongs to microwave circuit tuning field, is specifically related to have multichannel and distributes and the microwave circuit tuning of composite structure and the instrument of localization of fault.
Background technology
In modernization telecommunication products, especially use in the electronic telecommunication product of microwave radio amplifying technique, multichannel is distributed with the microwave circuit of composite structure comparatively conventional.Often need first to the dismounting of circuit self structure, welding in fault detect, change the configuration state of primary circuit, reduce the quality of product to a certain extent, hidden danger certain in the functional reliability existence of product.The present invention can not welding, dismounting multichannel distributes with under the prerequisite of the microstrip circuit of composite structure, carries out breakdown judge and location to short circuit.Effectively prevent repetition dismounting, weld impact on product quality.
Summary of the invention
In order to solve multichannel distribute the debugging of microwave circuit and the maintenance failure location of composite structure time, circuit repeated disassembled and assembled, welding are more easily caused to device failure and produce the problem of hidden danger of quality, and the utility model provides a kind of Microwave Measurement And Adjustment aid.
Concrete structural design scheme is as follows:
The probe 1 of Microwave Measurement And Adjustment aid uses the internal copper wire into radio-frequency cable 2, other one end of radio-frequency cable 2 adopts the method for welding to be welded on the welding end of female joint SMA connector 3, the other threaded one end end of connector 3, embeds microwave radio power absorption load 4 by spiral.
Advantageous Effects of the present utility model is
:
1, main body of the present invention is flexible radio frequency cable 2, its copper inner wire is good circuit probe 1, utilizes the pliability feature of flexible radio frequency cable 2, adapts to the project organization of microstrip circuit complexity, its main body is except probe 1, and radio-frequency cable 2, connector 3, load 4 can as effective grounding ends;
2, after flexible cable 2 welds with employing female joint SMA connector 3, thread end connects microwave radio power absorption load 4, can be convenient to disassemble replacing, to guarantee the maintainability of Microwave Measurement And Adjustment aid after load damages;
3, adopt the signal absorption principle of microwave circuit, use exclusive method under the prerequisite do not changed product self circuit, under namely not using the step prerequisite of dismounting, welding, realize the localization of fault work that multichannel microwave distributes combiner circuit.Avoid conventional fault detection and location repeated disassembled and assembled to a certain extent, weld the loss that device is reprocessed and microstrip circuit is scrapped that causes, improve the efficiency that Microwave Measurement And Adjustment and fault are reprocessed.This Microwave Measurement And Adjustment aid has that structure is simple, with low cost, easy and simple to handle, high, the portable advantage of localizing faults efficiency.
Accompanying drawing explanation
Fig. 1 is Microwave Measurement And Adjustment aid schematic diagram.
Fig. 2 is that Microwave Measurement And Adjustment aid uses schematic diagram.
Sequence number in upper figure: probe 1, radio-frequency cable 2, connector 3, load 4, microstrip circuit 5, microstrip circuit earth terminal 6.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
See Fig. 1, a kind of Microwave Measurement And Adjustment aid comprises probe 1, radio-frequency cable 2, connector 3 and load 4.One end of radio-frequency cable 2 is connected to probe 1, and the other end is connected to the welding end of connector 3, and described connector 3 thread end is connected to load 4.Load 4 is the load of microwave radio power absorption.Connector 3 is microwave radio signal connector.Probe 1 is the copper inner wire of radio-frequency cable.Radio-frequency cable 2, for having the flexible cable of metal screen layer, is connected with can making any metallic member and the circuit of this instrument except probe like this, can produce a good closed micro-strip loop, the effective microwave signal power absorbed in microstrip circuit.By observing the working condition of whole microwave radio circuit, reach judge this branch road whether fault object.
See Fig. 2, in actual measurement uses, probe 1 connects microstrip circuit 5, and radio-frequency cable 2 can 0
oto 180
obend arbitrarily within scope, and the external metallization shell of radio-frequency cable 2, connector 3, load 4 all can connect microstrip circuit earth terminal 6, effectively can be suitable for the requirement of various complicated microstrip circuit.
