Description
Technical field
The present invention relates to a kind of adjustable power couplers of impedance auto-match, belong to indoor mobile communication systems technology neck
Domain.
Background technology
Power coupler is applied to mobile communication field, such as connect high-power POI (combining system) realize large buildings and
The in-door covering of venue for another example connects high power transmitter and realizes that reduce signal strength wants to match fibre optic repeater input power
It asks.Requirement for a outstanding power coupler is considered as the following：
1, the power coupler degree of coupling cannot only have a degree of coupling, also answer adjustable, and adjustable coupling degree range needs enough
Greatly；2, the power degree of coupling should not can only weak coupling, it is also necessary to close coupling, it may be preferable to reach each port decile, that is, 3dB couplings
It closes；3, the strict demand due to certain occasions to power input value, the continuous adjustability to the degree of coupling are also important indicator, such as light
The input power of communication relays：4, the coupling frequency bandwidth of coupler should cover entire mobile communication frequency spectrum；5, main line inputs
Power can due to device standing wave performance by device itself it is different degrees of be reflected back input port, if coupler debugging when
Or occur larger standing wave value or standing wave saltus step when in some coupling position, it can damage transmitter because reflection power is excessive and make
At accident and loss.
Original adjustable technology needs to be realized with contact resilient component, processing difficulties, of high cost, more entire
The chieftain of adjustable part will movable length so that suitability is bad, and when adjusting is cumbersome, and can not be mounted on fixed sky
Between in position.Original adjustable power coupler can only realize 15-30dB due to that can not accomplish impedance matching in adjustment process
Weak coupling it is adjustable, when being transferred to close coupling can because impedance mismatching is excessive cause standing wave very poor and can not use, 6-15dB only
Fixed power Coupling Design can be used.
Invention content
The purpose of the present invention is：While realizing adjustable power coupling, ensure the power flatness in entire frequency range
And standing wave is good, improves the performance of system.
In order to achieve the above object, the technical solution of the present invention is to provide a kind of adjustable power couplings of impedance auto-match
The both ends of clutch, including main line, main line are respectively input port and output port, and by-pass coupling piece is equipped in the top of main line,
By-pass coupling piece is connected to coupled output ports, which is characterized in that the adjustable member that can be rotated around main line axis is equipped on main line
Device drives adjustable component to rotate, is coupled with by-pass when adjustable component is threaded to main line by actuating unit by transmission mechanism
It is maximum coupling when between piece, is most weak coupling when adjustable component is gone to below main line.
Preferably, the actuating unit is external rotation regulating switch.
Preferably, the transmission mechanism is gear driving pair.
The adjustable power coupler of impedance auto-match of the present invention may be mounted at fixed spatial position, when adjusting only
The knob on rotating panel is needed, it is convenient and efficient, by tuning component, can preferably be carried out while adjusting the degree of coupling
Impedance matching reaches the close coupling for the 6dB that original adjustable power coupler cannot achieve to realize that close coupling is adjustable.By right
The Optimal Structure Designing of rotor reaches the automatic locking for turning to any position rotor, really realizes the degree of coupling steplessization (continuous)
Tuning, standing wave is without saltus step when coupling tuning.
A kind of adjustable coupler provided by the invention realizes adjustable power coupling, and ensures in entire frequency range
Power flatness and standing wave are good, improve the performance of system, and fitted position position is constant, accelerate mobile communication indoors
What power coupled when system quickly realizes and brings facility, there is fabulous economic benefit and application prospect.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the adjustable power coupler of impedance auto-match provided by the invention.
Specific implementation mode
In order to make the present invention more obvious and understandable, hereby with preferred embodiment, and attached drawing is coordinated to be described in detail below.
As shown in Figure 1, a kind of adjustable power splitter provided by the invention includes main line 1, by-pass coupling piece 2, coupling output
Port 3, adjustable component 4 (rotor), gear driving pair 5.
Main line 1 is "-" type, and both ends are respectively input port and output port.It is defeated that by-pass coupling piece 2 is connected to coupling
Exit port 3, coupled output ports 3 are used for output coupling signal.There are one adjustable members for setting between main line 1 and by-pass coupling piece 2
Device 4.By rotating regulating switch in containment portion, gear driving pair 5 is driven to rotate, to drive adjustable component 4 around master
Line 1 rotates, and adjusts the degree of coupling by the rotation of adjustable component 4, realizes the power distribution of different proportion.Adjustable component 4
When being threaded between main line 1 and by-pass coupling piece 2, for maximum coupling (6dB), it is most weak coupling that adjustable component 4, which goes to 1 lower section of main line,
It closes (20dB).When adjustable component 4 is rotated arbitrary coupling is realized by optimizing the structure of cavity, main line 1 and adjustable component 4
Right impedance matching reaches main line outstanding standing wave performance while realizing 6-20dB power distribution adjustabilitys.
When adjustable component operates, each port position remains unchanged, the bandwidth of this design for input port, output port
It can be achieved from 694MHz to 2700MHz, and pass through impedance matching so that degree of coupling maximum can adjust the close coupling of 6dB
Also there is extraordinary standing wave when spending.It can be debugged to suitable power distribution in different frequency ranges according to power requirement, and ensure it
Size constancy is dynamic, and practicability is good.Its installation site need not be changed after encapsulation because of adjustable.
