What are the crystals used in 5G products?
2024/07/23
The Chinese government has repeatedly confirmed that 5G will be commercially available in 2020. Now, various technologies for 5G have been heating up rapidly, and many technical solutions have been gradually implemented.
So how much do you know about 5G? What the hell is 5G? What is 5G? The fifth-generation mobile phone mobile communication standard, also known as the fifth-generation mobile communication technology, foreign language abbreviation: 5G. It is also an extension after 4G and is under study. The network speed can reach 5M/S-6M/S. A brief summary of 5G is 4 sentences: low power consumption, high speed, low latency, and the interconnection of everything.
High speed: on the basis of 4G, the speed of Internet access can be increased by 100 times, reaching 20Gbps per second. Speed-up is very valuable to the technical and industrial fields. Such a high speed, on the one hand, means that the spectrum utilization rate is greatly improved, on the other hand, it conveys that some spectrum that was previously considered impossible to have commercial value can be used for mobile communication, which greatly improves the ability of human beings to develop mobile communication resources.
Internet of Everything: In the era with voice as the core, the number of links supported by mobile communication is very limited. At present, China's base stations only support about 1.2 billion terminals, that is, each person has one or two terminals. In the 5G era, each person may have 5 or even 10 terminals, and the number of devices linked to each base station will increase 5 or even 10 times. A large number of technology products will be connected to the network. This means that in the 5G era, the concept of Internet access will be completely forgotten, and networking is the norm, and a large number of technology products will always be connected to the network, providing various valuable data and becoming the basis of the smart Internet.
Low latency: For user commands, what 5G needs to do is to minimize the reaction time of the base station. Many users are used to waiting when using computers to surf the Internet and mobile phones to make calls. However, for intelligent services after 5G, the requirements are completely different. Use it to support navigation, an intersection, the response is slow, the user may cross the intersection, turn around, take a long time. Especially the intelligent transportation system, all cars are managed through the central control center. A one-second delay can lead to a series of car collisions. Therefore, low latency is a problem that 5G must solve.
Low power consumption: a large number of smart wearable products released this year, the basic idea is to connect through a mobile phone, and then communicate with the base station by the mobile phone, and send the data to the Internet. These products are basically impossible to connect to the base station. Because today's base stations mainly solve voice communication, even data is getting faster and faster, and high power consumption is natural. However, in the future, many technology products need to establish new channels to communicate with base stations. These channels do not provide high speed, but can provide low-power data communication at low rates. The emergence of 5G can solve this problem.
5G strong attack, so what is the impact on the crystal industry? We all know that the current technology is inseparable from the use of electronic components, which also led to the development of many electronic products, including crystal. Quartz crystal has a key role in communication equipment, widely used in a variety of time display and time control products.
The reason why the above-mentioned 5G communication can achieve such amazing progress is that there is no lack of the use of patch crystals. The 2016mm and 2520mm ultra-thin ultra-small patch crystals are suitable for mobile communication fields such as the reference clock of mobile communication terminals. The chip crystal oscillator has the frequency of the reference clock source for various mobile communications. The chip crystal oscillator has excellent electrical characteristics and environmental resistance. It is suitable for the field of mobile communications and meets the requirements of the high temperature reflow temperature curve of lead-free soldering.
