The cost of green laser pointer applying radio frequency is higher
There are two, three, four. Splitter; connectors N type sub-head (50Ω), SMA head (50Ω), and F head (75Ω) three, our company first used the N and SMA head. 18. Coupler: extracted from the main part of the signal channel devices. The fourth generation of green laser pointer is another technological innovation of the page turning green laser pointer.Divided by the size of coupling 5.10.15.20. DB different specifications; signal can be extracted from the base station power coupler (300W), the coupling can be selected from the 30 ~ 65dB in; coupler connector to use more N head. 19. Load: terminal in a circuit (such as amplifiers) or electrical output port, to receive electrical power yuan / devices, components or devices referred to as the load. The most basic requirement is that the load impedance matching and can withstand the power. 20. Circulator: the one-way signal transmission devices. 21. Adapter: the different types of transmission lines connected devices. 22. Feed line: high-frequency current is transmitted transmission line. The latest green laser pointer can remote control the computer and write letters on the wall as well. 23. Antenna: (antenna) is a form of high-frequency current or wave energy converted into electromagnetic waves transmitted out to the specified direction from a certain direction or to restore the high-frequency electromagnetic currents.
Automatic Identification Technology
Automatic device recognition technology is currently the development of a new technology quickly, the English name for AutomaticEquipmentIdentification, referred to as AEI. To choose a perfect green laser pointer people should firstly choose by its appearance. The basic idea of this technology through the use of some advanced techniques to achieve the various objects, people or equipment (personnel, materials) in different states (mobile, stationary or harsh environments) and automatic identification and management. Currently the most widely used automatic identification technologies can be divided into two areas: optical technology and radio technology aspects. People should choose a green laser pointer by well knowing its practical functions. One common application of optical technology in the product include: barcode and camera two categories. These two types of products have been widely used in people's daily lives, and has been well known. For example: barcode for commodity management, video capture for illegal vehicles.
