Description

The mobile phone isolator
Technical field
The present invention relates to a kind of information protection device, relate in particular to the mobile phone isolator that a kind of arch-rival's machine signal is divulged a secret and protected.
Background technology
Mobile communication is the electronic communication system of an opening, as long as corresponding receiving equipment is arranged, just can intercept and capture your call-information at any time and any place.Critical component chip on the present mobile phone; Basically be derived from import, wherein some mobile phone itself just has the function of hidden conversation, can be at No ringing, also have no under the situation of demonstration and change talking state into by holding state; Reveal information makes mobile phone become tapping device.
Fast development along with mobile communication technology; The mobile phone broadband access network has obtained using widely; Spy service can utilize the surfing Internet with cell phone function that target is controlled; Steal cell-phone internal information and site environment real time information, this will bring bigger threat and more serious harm to national security.
In in the prior art, military powers such as the U.S. have set up multi-level, comprehensive, big column, high three-dimensional electronic monitoring network system covering the whole world, utilize these to scout network, the electronic intelligence of collecting adversary or would-be-adversary widely.Like " Echelon " that American National security bureau sets up, the information of " echelon " systematic collection not only relates to military affairs, has also contained the every field that politics, economy, culture etc. concern national security.
Except the use of mobile communication equipments such as mobile phone being made strict qualification; Each country has all developed the corresponding mobile communication jamming device; Like Muscovite " Plain-3 " number, be used to suppress the mobile radio of any type of common and special purpose; Small-sized, portable " Rodiola " jamming equipment; Be used to suppress GSM 900/1800 (EGSM), AMPS/DAMPS, the SKIT-MP jamming equipment of standards such as CDMA.
The mobile phone signal isolator is exactly the equipment that is used to block the mobile communication signal, and traditional mobile phone signal isolator antenna adopts plate aerial or column antenna, and separately design and installation.Adopt traditional mobile phone signal isolator also to have following deficiency: one, because traditional mobile phone signal isolator antenna adopts plate aerial or column antenna, thereby all to exist volume big, Heavy Weight, defect of high cost.Two, between power amplifier and the antenna radio frequency connector need be set, increase cost.Three, owing to connect through radio frequency connector between traditional mobile phone signal isolator antenna and the power amplifier; The outer conductor that guarantees radio frequency connector is connected well with power amplifier ground; Must take into full account physical connection structure and the design details of power amplifier printed between connector and the power amplifier; Technology difficulty when having strengthened design difficulty and production causes the production cycle long.Four, the moulding respectively of the match circuit between antenna and power amplifier can not guarantee consistency of product during production in enormous quantities.Five, the antenna of conventional mobile phone signal isolator separates with power amplifier, causes the coupling between antenna, radio frequency connector and the power amplifier to be difficult to reach optimum state, exists line loss big, thereby reduces the service efficiency of mobile phone signal isolator.
Summary of the invention
The objective of the invention is to overcome the problems referred to above that existing mobile phone signal isolator exists; A kind of novel mobile phone isolator is provided; The present invention can save the radio frequency connector between power amplifier and the antenna; Also can when improving the product space utilance, improve antenna gain, can also guarantee the consistency of producing in enormous quantities.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
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; Said microstrip antenna is a plurality of, connects with corresponding power amplifier respectively, and said microstrip antenna and power amplifier printed is integrated is arranged in the same printed board.
Said printed board after integrated is arranged in the casing, and the chassis cavity surface forms the metallic reflection face of microstrip antenna.
Said microstrip antenna is connected with power amplifier through match circuit, and microstrip antenna, match circuit and power amplifier are disposable integrated.
Said printed board is arranged on to be supported on the heating panel.
Employing the invention has the advantages that:
One, the present invention also comprises microstrip antenna; Said microstrip antenna is a plurality of; Connect with corresponding power amplifier respectively; And said microstrip antenna and power amplifier printed are integrated to be arranged in the same printed board, and the radio frequency connector between power amplifier and the antenna that adopted this configuration saves also provides cost savings owing to having lacked radio frequency connector simultaneously.
Two, among the present invention; Said printed board after integrated is arranged in the casing; The chassis cavity surface forms the metallic reflection face of microstrip antenna, and resonant cavity of each band microstrip antenna duplexer is a metallic reflection face, reduces the interference unit volume; When improving the product space utilance, also improved antenna gain.
Three, among the present invention, said microstrip antenna is connected with power amplifier through match circuit, and microstrip antenna, match circuit and power amplifier are disposable integrated; Match circuit one-shot forming between microstrip antenna and power amplifier; Guaranteed the consistency of producing in enormous quantities, integrated through this, simplified production technology; Improve production efficiency, reduced production cost.
Four, among the present invention, said printed board is arranged on to be supported on the heating panel, improves the power amplifier heat dispersion, has guaranteed the support fixation and the radiating effect of the printed board after integrated.
Five, behind employing the present invention, can shield the base station down signal of 2G, each frequency range of 3G mobile effectively, be suitable for applying.
