Description
Technical field
Device is put the present invention relates to micro- more particularly to a kind of 4G cell phone signal is micro- puts device.
Background technology
Three big mobile network communication of China at present, 4G are the abbreviations of forth generation mechanics of communication, and G is generation（A generation）
Abbreviation.4G systems can be downloaded with the speed of 100Mbps, be dialled up on the telephone fast 2000 times than current, the speed of upload also can
Reach 20Mbps, and disclosure satisfy that requirement of nearly all user for wireless service.And in the price side that user pays close attention to the most
Face, 4G and fixed broadband network are equally matched in price, and charging mode is more flexible motor-driven, and user completely can root
Required service is determined according to the demand of itself.In addition, 4G can be in the place that DSL and Cable Modem are not covered with
Deployment, then expands to whole distract, provides easily communication network using mobile phone for us, but we are using mobile phone again
Shi Changchang will appear signal difference, can not call or called problem, such case only have operator to increase signal amplifier, will
Small-signal is amplified, and it is ubiquitous to be truly realized mobile communication service, and mobile communication may be implemented whenever and wherever possible.But it is existing
The micro-cells signal amplifier of technology can only individually support to move, unicom or the amplification of telecommunication handset signal will such as be supported
Multi-signal must use more complete equipments, this brings huge waste to user.
Patent of invention content
The technical problem to be solved by the present invention is to provide, a kind of 4G cell phone signal is micro- to put device.
Realize that the technical solution of above-mentioned purpose is as follows：
A kind of 4G cell phone signal is micro- to put device, including 4G cell phone signal receiving antenna, first duplexer, the second duplexer, first point
Frequency device and the second frequency divider, retransmitting antenna, controller, frequency-shift signaling generator, shift frequency power amplification circuit, pulse charge and discharge electricity
Road and signal synthesis circuit；Micro- device of putting further includes the first frequency divider being connect respectively with first duplexer and the second duplexer
With the second frequency divider, respectively by the first data feedback channel, the second data feedback channel is connect first frequency divider with the second duplexer,
Respectively by the first down going channel, the second down going channel is connected second duplexer with the second frequency divider, and first uplink is logical
Road and the first down going channel include the mobile low noise amplifier being sequentially connected, three net traffic filters, signal amplifirer and signal
After isolator, the amplified frequency-shift signaling and the pulse signal are overlapped, generate pulse frequency-shift signaling and export.
Further, the pulse output detection module is detected output frequency.
Further, the first duplexer and the microstrip power divider that the second duplexer is wired in parallel.
Structure of the invention is small and exquisite, simple installation, and the different complicated places of flexible configuration reply solve three net 4G cell phone signals and deposit
Blind area, weak area, the range of instability the problems such as；By mobile phone it is micro- put inside device increase frequency divider will move, unicom and telecommunications three
The client of a operator distinguishes, and is amplified respectively, saves resource.
Description of the drawings
Nothing.
Specific implementation mode
Embodiment:A kind of 4G cell phone signal is micro- to put device, including 4G cell phone signal receiving antenna, first duplexer, second pair
Work device, the first frequency divider and the second frequency divider, retransmitting antenna, controller, frequency-shift signaling generator, shift frequency power amplification circuit,
Pulse charge-discharge circuit and signal synthesis circuit；Micro- device of putting further includes being connect respectively with first duplexer and the second duplexer
The first frequency divider and the second frequency divider, first frequency divider passes through the first data feedback channel, the second data feedback channel and respectively
Two duplexers connect, and respectively by the first down going channel, the second down going channel is connected the second duplexer with the second frequency divider, described
The first data feedback channel and the first down going channel include the mobile low noise amplifier being sequentially connected, three net traffic filters, signal
After amplifirer and signal isolator, the amplified frequency-shift signaling and the pulse signal are overlapped, pulse shift frequency is generated
Signal simultaneously exports.
Wherein, the pulse output detection module is detected output frequency.
Wherein, the first duplexer and the microstrip power divider that the second duplexer is wired in parallel.
The preferred embodiment that these are only the embodiment of the present invention is not intended to limit the invention embodiment, all at this
Within the spirit and principle of inventive embodiments, any modification, equivalent replacement, improvement and so on should be included in of the invention real
It applies in the protection domain of example.
