Description
Technical field
The present invention relates to microwave regime, particularly a kind of multilayer Ba Lun.
Background technology
In RF application, the Ba Lun purposes is very extensive, and the place that any needs equilibrate to unbalanced transformation all needs to use, such as phase detector, single side-band modulator, balanced mixer and antenna etc.The Ba Lun of microstrip line construction, especially Marchand Ba Lun, simple because of its model analysis, be convenient to advantages such as coaxial line couplings and be widely applied.
Marchand Ba Lun is comprised of two sections identical coupling lines, and the length of every section coupling line is the quarter-wave at centre frequency place.Because Coupled Line Length of Band and the centre wavelength of Marchand Ba Lun are in same magnitude, therefore, its length is very long.If Marchand Ba Lun is produced on the plane, then its volume is larger.
Summary of the invention
The present invention proposes a kind of multilayer Ba Lun, and it is excessive to have solved prior art mini-bus human relations volume, is unfavorable in the integrated problem of other circuit element.
Technical scheme of the present invention is achieved in that
A kind of multilayer Ba Lun comprises top-level metallic ground and underlying metal ground; Metal screen layer has window on the described metal screen layer; Upper strata coupling line, described upper strata coupling line are between described top-level metallic ground and described metal screen layer, and an end of described upper strata coupling line is connected to described top-level metallic ground by upper grounding through hole; The wire connecting through hole, an end of described wire connecting through hole is connected to the other end of described upper strata coupling line, and described wire connecting through hole passes described window; And lower floor's coupling line, described lower floor coupling line is between described underlying metal ground and described metal screen layer, one end of described lower floor coupling line is connected to described underlying metal ground by lower grounding through hole, and the other end of described lower floor coupling line is connected to the other end of described wire connecting through hole.
Alternatively, described upper strata coupling line and described lower floor coupling line are symmetric about described metal screen layer.
Alternatively, described upper strata coupling line comprises the first segmentation and the second segmentation, and described the first segmentation and described the second segmentation are distributed on the different medium layer, and vertical arrangement.
Alternatively, described lower floor coupling line comprises the first segmentation and the second segmentation, and described the first segmentation and described the second segmentation are distributed on the different medium layer, and vertical arrangement.
