Abstract
The present invention provides a duplexer structure for an outdoor digital microwave unit, which comprises a platform beside a radio frequency receiving/sending module and two square wave interfaces symmetrically arranged at a front end and a back end of the platform. Wherein, these two square wave interfaces are positioned toward each other. Two square wave interfaces on the duplexer are connected with these two square wave interfaces to arrange the duplexer on the platform beside the RF receiving/sending module. A radiator shell is arranged on an upper cover of the duplex and fixed on the RF receiving/sending module through bolts. A round wave interface is arranged on the radiator shell and connected with a round wave-guide on the duplexer. The present invention has the advantages of easy duplexer detachment to replace a duplexer only by detaching the radiator shell on the duplexer, simple and reliable structure and greatly lower work volume, thus reducing cost and expense on duplexer replacement by 20% of total ODU price.
Description
Technical field
The present invention relates in a kind of digital microwave communication the structure of microwave transport equipment.
Background technology
Traditional digital microwave outdoor unit (ODU) is that duplexer is built-in, promptly is placed on the bottom of ODU, because the duplexer bandwidth of operation is narrower, in order to be applied to different service bands, ODU need change the duplexer of different performance requirement, like this, after needing all modules of dismounting ODU, could change duplexer, quantities is big, and damages module easily, change No. one time the duplexer expense, account for 40% of ODU total price.
Summary of the invention
For separating the problem of above-mentioned existence, the invention provides the structure of duplexer in a kind of digital microwave outdoor unit; This structure is on the radio-frequency (RF) receiving and transmission module next door one platform to be set, be arranged with two square wave guide interfaces before and after on the platform, corresponding with this square wave guide interface position, two square wave guide interfaces on the duplexer are connected with this Waveguide interface, duplexer is placed on the platform on radio-frequency (RF) receiving and transmission module next door,, and be fixed on the radio-frequency (RF) receiving and transmission module with screw at duplexer upper cover one radiator casing, radiator casing is provided with a circular waveguide interface, and is connected with circular waveguide on the duplexer.
Advantage of the present invention is that the dismounting duplexer is convenient, only needs the radiator casing above the dismounting duplexer, just replaceable duplexer, simple and reliable for structure, greatly reduced quantities, thereby reduced cost, changed No. one time the duplexer expense, can be reduced to about 20% of ODU total price.
Description of drawings
Accompanying drawing 1 is a three-dimensional exploded view of the present invention.
Accompanying drawing 2 is the front views after accompanying drawing 1 assembling.
Embodiment
See also shown in the accompanying drawing 1, this structure is on radio-frequency (RF) receiving and transmission module 3 next doors one platform 10 to be set, on the platform 10, front and back are arranged with two square wave guide interfaces 7, corresponding with these square wave guide interface 7 positions, two square wave guide interfaces 6 on the duplexer 2 are connected with this Waveguide interface 7, again by the screw 5 on screw 4 and the platform 10, duplexer 2 is placed on the platform 10 on radio-frequency (RF) receiving and transmission module 3 next doors, at duplexer 2 upper cover one radiator casing 1, and be fixed on the radio-frequency (RF) receiving and transmission module 3 with screw, radiator casing 1 is provided with a circular waveguide interface 8, and is connected with circular waveguide on the duplexer 2.
