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. Taking into account a radio communication system design complexity, the most favorable method is to first build a simple application, but can do a lot of adaptive improvements (such as support for multiple frequency) radio communication systems. If you use this method, you only need very little time available to establish a radio communication system, and can devote more time to deal with those designed for special needs.If you don’t use the receiver, you can put it into the green laser pointer body. For example, a range of DC to 10GHz power detector can be applied to any wireless standard. If you use more accurate, more stable (eg, temperature stability), high-quality components, and related applications and does not require such high accuracy and stability, which will undoubtedly increase the cost of the design. Whenever possible, use a single device may be able to fully offset the cost of other parts and a slight surplus. At the same time, there may shorten design-to-market time. The basic feature is the lower cost of electronic tags, labels the amount of data stored within a small, short reading distance (passive case, the typical reading distance of 10cm) form a variety of electronic tags (card-shaped, circular, button-like, pen-like), read the directional antenna is not strong.green laser pointer shortens the distance between teacher and students High-frequency systems generally refers to the operating frequency greater than 400MHz, the typical frequency of operation are: 915MHz, 2450MHz, 5800MHz and so on. High-frequency systems in these bands also have a large number of international standards to support it.
