The performance of the cell phone signal jammers

 The performance of the cell phone signal jammers can be raised to a higher level.
The multimeter amount of the beginning and end of the microstrip line is the same, but should not be a starting point and end point is short. Microstrip line structure is shown in Figure 2-2. Ordinary diode is a diode of the one-way conductive work, two pins, usually black, at one end thereof a white vertical line, that the final is negative. Zener diode voltage regulator for short, the work is the use of diode reverse breakdown characteristics. In the mobile telephone circuit, it is often used in the receiver (speaker, a speaker) circuit, the vibrator circuit and ringtones circuit. As a circuit in the mobile phone receiver, a buzzer and a vibrator of the coil, these circuits work, due to the induced voltage of the coil, resulting in a high peak reverse voltage. The quality and performance, can guarantee a cell phone signal jammers, cell phone signal jammers can maintain the advanced nature development.And
The light-emitting diode work in forward bias state. In normal circumstances, the forward voltage of the light-emitting diode, in the 1.5-3V. In addition, there are also some special light-emitting diodes, such as an infrared diode. The growing number of mobile phone use infrared light-emitting diode, which is used for infrared transmission. A combination of the so-called diode, i.e., constituted by a plurality of diodes diode module circuit. D107 Samsung A288 phone switch control circuit is a combination of the diode, the internal concentration of the four diodes together to form a modular structure, the kind of the internal circuit structure and shown in Figure 2-3. Combination of the diode, three-legged, four-legged, diode combination, Samsung mobile phones in more frequent use, I do not intend to analyze. Suppliers should pay attention to the technical reform, cell phone signal jammers.
You find your file, view its properties, you can see the file types, such as wav files for audio / x-wav, and then determine, only by such a set up to receive just the right to open the file you send, otherwise it is impossible to set up another. The software has built-in common file set the shortcut menu, select "Set image," Set Audio "is set to the video in the appropriate format. This step is crucial, can not set up correctly, the receiver is unable to open the file you send. 3GP, MP4 format full screen playback the device pvplayer use. If you like the 3GP format video files, but do not like the machine comes with the player (the screen is too small). The company held a meeting to discuss the development direction of phone jammer .
