Description

A kind of new high intermodulation electric bridge bonder

Technical field

This utility model is related to coupler technologies field, more specifically, particularly to the new high intermodulation electric bridge coupling of one kind Clutch.

Background technology

Now widely used 3dB electric bridge and bonder are individual devices, and its frequency is between 698-2700MHz, With the development of this technology, communication technology is required, the integrated level of equipment and space availability ratio are more and more highers, in conventional 698- The passive product such as the electric bridge of 2700MHz frequency, bonder, power splitter, load, attenuator, not only carry according to application scenarios difference High power range, even more proposes the requirements at the higher level such as third order intermodulation, and wherein electric bridge, bonder are the most substantially it is proposed that more High spatial volume reduces, high power and third order intermodulation etc. require, and if complete in the electric bridge and bonder of 698-2700MHz Portion realizes these requirements, is difficult to realize, requirement that high-power, and operating frequency is broadband, so can not be set using microstrip line Meter, the metal copper foil thickness of microstrip line is difficult to bear high power it is important to cannot be carried out electric bridge and bonder on space structure Merge, furthermore also will third order intermodulation etc. be required need to meet.For this reason, it is necessary to a kind of new high intermodulation electric bridge coupling of design Device.

Utility model content

The purpose of this utility model is to provide a kind of new high intermodulation electric bridge bonder, and it not only increases space structure Utilization rate, and high-power and good third order intermodulation can be born, both meet needs functionally, and reduced production Cost.

In order to achieve the above object, the technical solution adopted in the utility model is as follows：

A kind of new high intermodulation electric bridge bonder, including inner cover plate, outer cover plate, strip line, medium clamping plate, one-level coupled zone And capillary groove；Described inner cover plate upper end is provided with cavity, and described cavity upper end is provided with outer cover plate, described strip line in cavity, The upper and lower of described strip line is equipped with medium clamping plate, and described strip line includes one-level coupled zone.

Further, described one-level coupled zone and bridge output parallel coupling.

Further, the thickness of described strip line is 2mm.

Compared with prior art, the utility model has the advantage of：This utility model not only increases the profit of space structure With rate, and high-power and good third order intermodulation can be born, both meet needs functionally, reduced production cost again.

Brief description

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.

Specific embodiment

Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model Define.

Refering to shown in Fig. 1 and Fig. 2, this utility model provides a kind of new high intermodulation electric bridge bonder, including inner cover plate 2, Outer cover plate 3, strip line 4, medium clamping plate 5, one-level coupled zone 6 and capillary groove 7；Described inner cover plate 2 upper end is provided with cavity 1, described Cavity 1 upper end is provided with outer cover plate 3, and in cavity 1, the upper and lower of described strip line 4 is equipped with medium clamping plate to described strip line 4 5, and described strip line 4 includes one-level coupled zone 6.

Preferably, described one-level coupled zone 6 and bridge output parallel coupling, end terminates.

Preferably, the thickness of described strip line 4 is 2mm.

Medium clamping plate 5, when using, is first installed on bottom fixed position in cavity 1, then will carry again by this utility model Shape line 4 is arranged on above medium clamping plate 5, adjusts position in cavity for the strip line 4, welds each node simultaneously, and node welds Connect and require smooth, full, installation inner cover plate after adjustment good position, with screw-driving, cavity and inner cover plate form tight inner chamber, whole The closure of individual inner chamber 1 is good, the contact with cover plate for the cavity closely so that the third order intermodulation performance of electric bridge bonder reach- 155dBc, then upper cover plate screw-driving is installed.

This utility model not only increases the utilization rate of space structure, and it is mutual to bear three high-power and good ranks Adjust, both met needs functionally, and reduced production cost again.

Although being described in conjunction with the accompanying embodiment of the present utility model, patent owner can want in appended right Various modifications or modification is made, as long as less than the protection model described by claim of the present utility model within the scope of asking Enclose, all should be within protection domain of the present utility model.
