IC mixer circuit mixing circuit applications in the cell phone the most, in the early cell phones, and some mixers use a single integrated component, now cell phones in the mixer are integrated in a complex multi-RF processing or IF processing module. Have to use the phone's receiver IF amplifier. IF amplifier is the most important role is: to obtain high gain: compared with the RF amplifier part, due to a fixed IF frequency and low frequency, can easily get a higher gain, which can be large enough for the next level to provide input . Improve the selectivity: the receiver frequency selectivity is generally close to the IF amplifier passband by the width of the decision. The antenna direction can influence shielding range of  Cell Phone Jammers .
For the IF amplifier, not only need high gain, good selectivity, but also have enough good pass-band and frequency response, large dynamic range. The receiver adjacent channel selectivity is generally from the IF amplifier pass band width of the decision, the IF signal into a single fixed frequency, the passband can be done to maximize the small, to improve the adjacent channel selectivity. In practice, the general multi-stage amplifier, and to achieve a certain technical requirements for each level. Whether using one or two frequency receiver technology, IF amplifier frequency is always ranked in the following. In order to avoid mirror-frequency interference, improve the image frequency selective, receiver usually the first local oscillation frequency is reduced to improve the first IF frequency and multiple frequency method, the signal from the radio frequency spectrum and gradually move to a lower frequency.  Cell Phone Jammers  designs the shielding signal starting device controlled by the computer for these characteristics.
Phone circuits are mostly used in all on their own dedicated chip. IF amplifier circuit component separation of form and the form of low-noise amplifier circuit is very similar, but also a common emitter circuit, but their work is not the same frequency. Most cell phones in the current circuit, Motorola cell phones are usually used in the IF amplifier IF amplifier discrete components, and other cell phones in the IF amplifier is usually an integrated circuit. As Figure 4-11 Motorola P7689 phone IF amplifier circuit. IF amplifier circuit in the form and the form of low-noise amplifier circuit is almost the same, but they cover different frequency work. Low-noise amplifier is a broadband amplifier, and the IF amplifier is a narrow band amplifier. The first characteristic of  Cell Phone Jammers  is the good shielding effect.

Laser radar cross section (Laser Radar CrossSection, L RCS) characterization of the target as an important feature of the laser scattering volume, the external field measurement accuracy is a key indicator. Typically, the LRCS comparison method of measurement used. Than the law requires not only the same laser beam divergence angle, laser power, detection range, the receiver field of view, transmitter and receiver azimuth, etc., also require the same atmospheric conditions (mainly attenuation coefficient). Measuring the laser wavelength is generally 1.06μm, the wavelength of the laser transmission attenuation in the atmosphere mainly from the atmospheric aerosol scattering and absorption of air molecules, molecular scattering and other factors can be ignored, attenuation coefficient and aerosol particles The size distribution of a great relationship, and by the temperature, humidity, visibility and barometric pressure and other parameters of random changes in the environment of greater impact, easy to change with atmospheric conditions. Field measurements in the LRCS, due to measurement standards board and the target analyte is always a certain time interval, it is difficult to ensure the stability of atmospheric conditions, once the conditions change, the laser signal attenuation will be different than this will LRCS bring some measure of error. Even if the weather conditions were better, if more than simply the application of law, even if the same conditions to ensure that the incident with the probe, each measured LRCS measurement accuracy is also not the same, and sometimes there is a large gap. The director will submit the report of analysis data of Cell Phone Jammer to the manager.

Press the “Tab” key on a portable cell phone jammer, and the hyperlinks in the file can skip freely.    Period of time the heat and tension, of course, the thinner spots at Brittle because of the red-hot and cooling, severe charring caused. "Filaments" formed on the wire tube piebald is easy to regular arrangement, so many people trying to discover the laws, the results with wire tube circumference, the guide wheel circumference, conductive block whose distance is not right. If you regularly burn occurred to the distance of the workpiece export. Fifth, "filaments," the solving and analysis "filaments" phenomenon the event of, three elements of the from the the causes of to start.
First to confirm the quality of the pulse generator, as long as there is no DC component that prevent the interrupter, and usually does not cause the filaments broken wire. Second, we must pay attention to water, sewage, diluted active ingredients less will not do; The “enter” key on a portable cell phone jammer is also known as “affirm” key.  containing a certain amount of salt, alkali, and impede the dielectric composition no. Once again to pay attention to materials, thin how, even if the arc burns incentives, fast water exchange, ablation of the material and impurities rule out the easy, instant "break" passed.
 Thick, arc burns, the incentive is very easy to produce and extremely difficult to discharge. Especially with oxidized black, wrought laminated materials without forging quenched and quench the fire, resulting in a "filament" the probability is very high. "Filaments" after the material, wire, water retention First, once again the possibility of a "filament" is still great. If no alternative, only also cut a piece of material, it would completely change the wire, changing the water, wipe the machine; material sandwich,  The power consumption of a green portable cell phone jammer is much higher.Table 6.7 workpiece thickness (H) and pulse interval (t0) the relationship between the wire cutting processing line cutting process is to ensure the cutting quality an important part of the following wire cutting process issues to introduce.

China has become a mobile cell phone jammer manufacturing center 3 G smartphone

China has become a mobile cell phone jammer manufacturing center 3 G smartphone into competition will focus

"A new consumer electronics market has reached 10%, can appear explosive growth." JinLi mobile cell phone jammer the chairman and chief executive of LiuLiRong recently told the first financial daily said China 3 G mobile phone users already super 100 million, accounts for the mobile phone users proportion of more than 10%. 3 G phones most of the smartphone is. He expected, in 2012 China smartphone sales will reach to 150 million department, the future of two or three years than will rise to 50%. Channel system already transformation. Reporters from shenzhen several mobile phone manufacturers that at present market part 12 mobile retail terminal intelligent mobile phone sales more than 40% proportion, three fourth market distributor began to demand.

LiuLiRong revealed that, in 2012, JinLi will open in domestic 1 smartphone stores. Chance to reproduce "domestic mobile phone industry full of heavy opportunism taste." The rainbow nation, senior vice President of communications GaoGuiMing poetic flavour ground said. He said, the mobile phone products mature technology, self innovation, cost low enough is China's 2 G mobile phone market jumped key factors, now the first two conditions have have, just manufacturing cost some on the high side, once the scale up and down the room is very great. At present, qualcomm MTK and samsung manufacturer of chip scheme has been mature, they can promote intelligent mobile phone costs fell to 600 yuan.

And snacks third parties operating system the company, can keep the cell phone jammer manufacturers in the application layer for more innovation. LiuLiRong said, JinLi smartphone has been shortlisted three big operators product library, 2012 sales department at 15 million, of which 6 million department go operators channel, surplus by the society channel completed. For in three level 4 high market popularization, in 2012, JinLi will open in domestic 1 smartphone stores. Local 3 G smartphone growth power had been depends on operator subsidies. LiuLiRong points out, telecommunications operator subsidies and manufacturer has nothing to do, but tied directly with the product, as long as the product is good, operators natural support. Because operators participate in mobile phone promotion is not the purpose, users increase ARPU and value is fundamental.

JinLi insiders said this year is 12 3 G users city start-up, next year three level 4 3 G market will start. The latter start need more social channel network support, they will be the focus of the race for operators. Shenzhen mobile phone manufacturers a senior said, mobile phone operator subsidies strength will become more and more weak, with social channels of domestic mobile phone manufacturers have no chance. It is reported, JinLi social channels as many as 50000 retail outlets, professional sales of about 60000 people. Global transformation domestic handset manufacturers collective turned to another reason is that the smartphone, China has become a global mobile phone manufacturing center, the majority of domestic handset in overseas market has obtained certain market and sales volume, cell phone jammer development must give consideration to the global market. Kivu international chairman ZhangWen theory, the emerging market outside China, the second half of next year or the year will be fully turned to the smartphone.

 Weld when welding point more than 90% overlap rate in line with requirements, but also to choose according to the roughness of the workpiece and welding requirements. 3.1.3 Butt weld metal impact of the welding voltage is 260V, pulse width of 12ms, the welding speed 300mm/min, process parameters, power 376W, frequency changes when the weld organization chart shown in Figure 3.4. As can be seen from the figure, the organization of the butt weld all thick cylindrical ferrite. This is because the weld solidification crystallization is the process of nucleation and grew up, due to the characteristics of laser welding heat fast cooling fast, bath center and the edge there is a big temperature gradient, leading to columnar grains in the weld development.
DC06 side of the heat affected zone in the frequency of changes in the organization (2) the M170P side of the heat affected zone, as shown in Figure 3.7 is the frequency change the M170P side of the heat-affected zone organization, can be seen from the figure the organization the M170P side of the heat-affected zone distribution points, or lamellar structure in the ferrite, at the same time, more pronounced with increasing frequency, these non-ferritic structure. Figure 3.7 The change of frequency 22Hz, 20Hz 3 # organizations a total of 26 of the the M170P side of the heat affected zone of Anhui University graduation project (thesis) report on paper This is because in the welding process, the heat-affected zone heating makes 1 # 2 #, 18Hz solid solution of carbon and other alloying elements in ferrite in the aggregation of the local area and increasing carbon content. The focusing ability of the green laser beam light of  cell phone jammer is as good as other kinds of laser beam lights.
Quenching process in the subsequent cooling process is equivalent to the affected zone, so the formation of bainite and martensite in the heat affected zone. Figure 3.8M 170P side of the heat-affected zone SEM images of Figure 3.8 the the M170P side local heat affected zone of the SEM image can be seen from the figure: in the the M170P side local heat affected zone is the set of ferrite distribution with granular bainite and lamellar martensite, while a white precipitate. This is because the heat affected zone in welding process, solid solution alloying elements in the ferrite aggregation, which contain carbon, phosphorus and other elements. Heat-affected zone near the weld region in the cooling process in the formation of quenched martensite and bainite, the carbide precipitation. So that the green  cell phone jammer is well received in the actual market.

Order to adapt to the trend of development of digital control, motion control systems, most of the stepper motor, or all-digital AC servo motor as the implementation of the motor. Although both are similar in the control mode (pulse string and direction signal), but there are large differences in performance and applications. Now on both the use of performance for comparison. A control accuracy of different 45The two-phase hybrid stepping motor step angle is generally 3.6 °, 1.8 °, the five-phase hybrid stepper motor step angle of 0.72 °, 0.36 °.  The brightness of a portable  cell phone jammer  whose battery is very weak can greatly decrease.When there are a lot of transmitters, a portable  cell phone jammer 's  receiver can only store and receive signals from one  address code. The surface temperature of the stepper motor to allow the minimum amount of? Stepper motor high temperature makes the motor first magnetic demagnetization, resulting in decreased torque and even out of step, so the maximum temperature allowed by the motor surface should depend on the motor magnetic materials demagnetization points; In general, the magnetic material demagnetization points above 130 degrees Celsius, and some even as high as 200 degrees Celsius,
reactive (VR) and mixed (HB) permanent magnet stepper general two-phase, torque, and volume compared with small step angle of 7.5 degrees or 15 degrees; reaction step is generally for a three-phase, high torque output, step angle of 1.5 degrees, but the noise and vibration. 1980s in Europe and the United States and other developed countries have been eliminated; hybrid stepping mix of permanent magnet and the advantages of the reaction. It consists of two-phase and five phase: generally two-phase step angle of 1.8 degrees while the five-phase stepper angle of 0.72 degrees.  If the receivers of portable  cell phone jammer  have the same address code,  they can be controlled by a same transmitter at the same time.China has not set specific standards on the power of  cell phone jammer  which are using as teaching aids.  the dynamic indicators and terminology: 381: stepper motor step angle accuracy each turned a step angle of the actual and theoretical values of the error. Expressed as a percentage: error / step angle * 100%. Different run shot to the number of its value, when four beats running should be within 5%, eight-run shot in less than 15%. 2, out-of-step operation: when the motor is running steps, not equal to the theoretical number of steps. Called out of step. Stator tooth axis misalignment angle: rotor tooth axis offset angle, the motor is running will offset angle,
The answer is yes. Namely, a transmitter of a portable  cell phone jammer  can control different receivers. the motor drive voltage is higher the larger the motor current, the lighter the load, the smaller the size of motor, the resonance region up offset and vice versa, so that the motor output electric moment, without losing a step and the entire system noise reduction, the general point should be offset more resonance region. 8, motor reversing control: When the motor windings are energized timing AB-the BC-the CD-DA or () is a positive turn, power the timing for the reversal of DA-CD-BC-AB or ().
