Abstract
The utility model belongs to microwave communication equipment, and relates to a microwave passive module, in particular to a diplexer. The diplexer comprises a plurality of two-in-one combiners; each combiner comprises two sets of isolators and cavity filters in series; each isolator has an input end connected with a transmitter; output ends of two cavity filters are both connected to the same first-order adapter; two sets of isolators and cavity filters and one first-order adapter are jointly arranged in the same shell; an output end of the first-order adapter in each two-in-one combiner is connected to a second-order adapter; the second-order adapter is connected with an antenna. The diplexer can offer that a plurality of transmitters and receivers share one antenna, thereby reducing antenna erection difficulty and raising equipment operational reliability.
Description
Technical field
The utility model belongs to microwave communication equipment, relates to a kind of microwave passive module that is used for, and specifically is a kind of antenna multicoupler.
Background technology
In traditional microwave communication equipment, when the multi-section transmitter and receiver uses simultaneously, need set up separately emission or reception antenna respectively, not only increase the difficulty of equipment construction, the while is wanted signal meeting phase mutual interference between the antenna more and influences reliability of operation.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of and can supply the shared antenna of multi-section transmitter and receiver, thereby can reduce the antenna installation difficulty, improve the antenna multicoupler of equipment operation reliability.
Antenna multicoupler of the present utility model includes several two-in-one mixers, described two-in-one mixer comprises the isolator and the cavity body filter of two groups of series connection, each isolator has the input that is connected with a transmitter, the output of two cavity body filters all is connected on the same first order adaptation, and two groups of isolators and cavity body filter and an one-level adaptation are installed in the same housing jointly; The output of the first order adaptation in each two-in-one mixer all is connected on the second level adaptation, the output of second level adaptation is connected with antenna through third level adaptation, and described third level adaptation also is connected with receiver through filter for receiver.
The utility model has been owing to can simplify greatly and reduce installation difficulty with the signal of multi-section transmitter and receiver through closing behind the road by an antenna emission or receiving, simultaneously can the phase mutual interference through the multiple signals of overmatching, improved the operational reliability of equipment; In addition, the modular construction of two-in-one mixer has also been simplified installation and transportation, has improved the versatility of equipment.
Description of drawings
Fig. 1 is the structured flowchart of the utility model embodiment.
Embodiment
As shown in the figure, this antenna multicoupler comprises that two have the two-in-one mixer 1 of housing separately, two-way cavity body filter in each two-in-one mixer receives the signal of two transmitters respectively by isolator separately, mates output then in same first order adaptation.The signal of two two-in-one adaptation outputs is again through a second level adaptation coupling output.The output signal of second level adaptation is connected with an antenna 2 through third level adaptation, and third level adaptation also is connected with receiver through filter for receiver, to realize received signal and the coupling that transmits.
