Description
Technical field
The present invention realizes that the device of frequency selection function is relevant with transceiver antenna.
Background technology
Duplexer is incorporated to receiving by signal lotus root by antenna, again launches signal by antenna, it is desirable to connect
Sending and receiving transmit-receive radio road each completes its function without influencing each other, and receives, influencing each other to depend primarily between radiating circuit connects
The suppression between transmitting is received, it is strong to suppress more high anti-jamming capacity.There was only a duplexer in usual communication system.But with
The development of technology and the needs of business, two duplexers are needed in multiple systems after an antenna synthesizes while are received and dispatched,
And phase differs 90o between two-way, existing duplexer can not meet existing system requirement.Existing duplexer mainly have with
Lower weak point：
1. a single duplexer can only meet that a system uses；
2. all it is that same-phase does not have phase difference between duplexer, it is impossible to meet some system needs phase differences 90o；
3. conventional duplexer only has an input.
The content of the invention
It is an object of the invention to provide a kind of small volume, function is more, two duplexers are synthesized by an antenna, and can
Used simultaneously in multiple systems, phase differs 90o between same group of duplexer, and conventional one input of duplexer is become
Two inputs, become after two inputs with two interfaces of any switching laws and indices qualified input and output can be ensured
Port differs 90o duplexer.
What the present invention was realized in：
Input and output port differs 90o duplexer, and the 1st, the 1st, 2 inputs with 90o electric bridges respectively of the common ports of 2 duplexers
Port 1,3 connects, and the 1st input port 1 of electric bridge passes through the 1st transmission line TL1, the 1st coupling line TL5, the 2nd transmission line TL2 and electricity
1st output port 2 of bridge connects, and the 2nd input port 3 of electric bridge passes through the 3rd transmission line TL3, the 2nd coupling line TL5, the 4th transmission
2nd output port 4 of line TL4 and electric bridge connects.
The resistance of 1-4 transmission lines is 50 Ω, and the resistance of 1-2 coupling lines is 50 Ω.
The present invention is achievable to be had the beneficial effect that：
Small volume of the present invention, function are more, two duplexers are synthesized by an antenna, and can made simultaneously in multiple systems
With phase differs 90o between same group of duplexer, and conventional one input of duplexer is become into two inputs, becomes two
With two interfaces of any switching laws and it can ensure that indices are qualified after individual input.The present invention has turned out to be feasible by experiment
, present invention process is reliable, is assembling, also very simple during debugging.It can greatly reduce the volume of product, and function is also significantly
Lifting.More spaces have been conceded on complete machine and weight and cost all it is big reduce it is many, even if volume reduce but
Other electrical performance indexes do not become, and index is reliable and stable during use, and the frequency range of passband can also be according to reality
Demand enters Curve guide impeller.The present invention is to belong to pure passive device, mainly by a 90o electric bridge and two existing duplexer groups
Into 90o electric bridges form phase difference after mainly two duplexers are synthesized, public after being connected together with two dualduplexers
Hold and interchangeable be connected in multiple systems and be mutually independent of each other.This side to be connected together with 90o electric bridges and dualduplexer
Case so that 90o electric bridge all can make whole performance with what is adjusted together with single adjustability and entirety with dualduplexer with tonality
Greatly improved with function, and existing convention duplexers can only be done with the situations of 90o phases and had breakthrough.

Embodiment
Input and output port differs 90o duplexer, the 1st, the common ports of 2 duplexers respectively with 90o electric bridges the 1st, 2
Input port 1,3 connects, and the 1st input port 1 of electric bridge passes through the 1st transmission line TL1, the 1st coupling line TL5, the 2nd transmission line TL2
It is connected with the 1st output port 2 of electric bridge, the 2nd input port 3 of electric bridge passes through the 3rd transmission line TL3, the 2nd coupling line TL5, the 4th
2nd output port 4 of transmission line TL4 and electric bridge connects.
The resistance of 1-4 transmission lines is 50 Ω, and the resistance of 1-2 coupling lines is 50 Ω.
This 90o dualduplexer is mainly made up of duplexer 1, duplexer 2 and 90o electric bridges, is energy the characteristics of this structure
Two duplexers is synthesized a dualduplexer and the phase between the transmitting or reception of same group of duplexer can be made to differ 90o
（As shown in Figure 1）.
1. signal is just divided into two-way by duplexer 1 and duplexer 2 after common port and 90o electric bridge combinings, output 1 and defeated
Go out 2, and can access two systems and work simultaneously, and be mutually independent of each other, this mode changes that conventional system can only
The function of a duplexer is accessed, just an original system of energy communicates by increasing a 90o electric bridge in dualduplexer front end
Capability improving is to two systems communication capacity.
2. output 1 and output 2 are the output ports of 90o electric bridges, electrical bridge principle figure（As shown in Figure 2）, signal is from port1 ends
Mouth passes through 50 Ω transmission line TL1, is then coupled to other 3 tunnels by coupling line TL5 again and is input to it again by TL2, TL3, TL4
On his 3 ports, wherein port1 ports to port2 port phases are 90o；Port1 ports differ 90o to port3 ports, therefore
When after port2 and port3 are tapped into duplexer 1 and duplexer 2 by electric bridge combining also with regard to 90o can be differed.
3. the operation principle of this duplexer（As shown in Figure 3）, two-way is divided the signal into behind port 1 and forms a duplex
Device.Resonator 1 wherein all the way is connected with resonator 2, is then connected again with resonator 3, resonance 4, defeated finally by port 2
Go out.The resonator 5 of another way is connected with resonator 6, is then connected with resonator 7, resonance 8, is exported finally by port 3 again.
