Description

Mobile phone isolator
Technical field
The present invention relates to a kind of information protection device, particularly relate to a kind of arch-rival's machine signal and to divulge a secret the Mobile phone isolator carrying out protecting.
Background technology
Mobile communication is the electronic communication system of an opening, as long as there is corresponding receiving equipment, just can intercept and capture anyone call-information at any time and any place.Critical component chip on current mobile phone, substantially be derived from import, wherein some mobile phone inherently has the function of hidden call, can when No ringing, also without any display change talking state into by holding state, reveal information, makes mobile phone become tapping device.
Along with the fast development of mobile communication technology, mobile phone broadband access network is widely used, spy service can utilize surfing Internet with cell phone function to control target, steal cell-phone internal information and site environment real time information, this will bring larger threat and more serious harm to national security.
In in prior art, the military powers such as the U.S. have set up multi-level, comprehensive, large column, high three-dimensional electronic monitoring network system covering the whole world, utilize these to scout network, collect the electronic intelligence of opponent or would-be-adversary widely.As " Echelon " that U.S.National Security Agency sets up, the information of " echelon " systematic collection not only relates to military affairs, also covers the every field of the relation national security such as politics, economy, culture.
Except making except strict restriction to the use of the mobile communication equipments such as mobile phone, every country has all developed corresponding mobile communication jamming equipment, as: Muscovite " Plain-3 " number, for suppressing the mobile radio of any type of common and special purpose; Small-sized, portable " Rodiola " jamming equipment; For suppressing GSM900/1800 (EGSM), the SKIT-MP jamming equipment of the standards such as AMPS/DAMPS, CDMA.
Cell phone signal isolator is exactly the equipment for blocking mobile communication signal, and traditional cell phone signal isolator antenna adopts plate aerial or columnar antenna, and separately design and installation.Traditional cell phone signal isolator is adopted also to there is following deficiency: one, because traditional cell phone signal isolator antenna adopts plate aerial or columnar antenna, thus all to there is volume large, Heavy Weight, the defect that cost is high.Two, need between power amplifier and antenna to arrange radio frequency connector, add cost.Three, owing to being connected by radio frequency connector between traditional cell phone signal isolator antenna and power amplifier, be connected good with ensureing the outer conductor of radio frequency connector and power amplifier, the design details of physical connection structure between connector and power amplifier and power amplifier printed must be taken into full account, technology difficulty when increasing design difficulty and produce, causes the production cycle long.Four, the match circuit between antenna and power amplifier is shaping respectively, can not ensure the consistency of product during production in enormous quantities.Five, the antenna of conventional mobile phone signal isolator is separated with power amplifier, causes antenna, coupling between radio frequency connector and power amplifier is difficult to reach optimum state, there is line loss large, thus reduce the service efficiency of cell phone signal isolator.
Summary of the invention
The object of the invention is to the problems referred to above overcoming the existence of existing cell phone signal isolator, a kind of novel mobile phone isolator is provided, the present invention can save the radio frequency connector between power amplifier and antenna, also can while raising product space utilance, improve antenna gain, the consistency produced in enormous quantities can also be ensured.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of Mobile phone isolator, comprise control unit and auxiliary circuit unit, power amplifier and power amplifier printed, it is characterized in that: also comprise microstrip antenna, described microstrip antenna is multiple, connect with corresponding power amplifier respectively, and described microstrip antenna and power amplifier printed is integrated is arranged in same printed board.
Described integrated after printed board be arranged in casing, chassis cavity surface forms the metal mirror of microstrip antenna.
Described microstrip antenna is connected with power amplifier by match circuit, and microstrip antenna, match circuit and power amplifier are disposable integrated.
Described printed board is arranged on and supports on heating panel.
Employing the invention has the advantages that:
One, the present invention also comprises microstrip antenna, described microstrip antenna is multiple, connect with corresponding power amplifier respectively, and described microstrip antenna and power amplifier printed is integrated is arranged in same printed board, adopt this structure to save radio frequency connector between power amplifier and antenna, also provide cost savings owing to having lacked radio frequency connector simultaneously.
Two, in the present invention, described integrated after printed board be arranged in casing, chassis cavity surface forms the metal mirror of microstrip antenna, each frequency channel microstrip antenna shares a resonant cavity and metal mirror, reduce interference unit volume, while improving product space utilance, also improve antenna gain.
Three, in the present invention, described microstrip antenna is connected with power amplifier by match circuit, microstrip antenna, match circuit and power amplifier are disposable integrated, match circuit one-shot forming between microstrip antenna and power amplifier, ensure that the consistency of production in enormous quantities, integrated by this, simplify production technology, improve production efficiency, reduce production cost.
Four, in the present invention, described printed board is arranged on and supports on heating panel, improves power amplifier heat dispersion, ensure that integrated after the support of printed board fix and radiating effect.
Five, after adopting the present invention, effectively can shield the base station downlink signal of 2G, each frequency range of 3G mobile, be suitable for applying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Be labeled as in figure: 1, control unit and auxiliary circuit unit, 2, power amplifier, 3, microstrip antenna, 4, printed board, 5, casing, 6, metal mirror, 7, match circuit, 8, support heating panel.
