What are the areas of application of microcontrollers?
The microcontroller was born in the 1970s and has been in development for over fifty years. From the initial 4-bit microcontroller to the current 8-bit microcontroller, 16-bit microcontroller and 32-bit microcontroller, as well as in the high-end field of microcontroller 64-bit microcontroller. The scope of application of microcontroller is also gradually expanded, nowadays, the application of microcontroller covers almost every corner of people's daily production life, where there is the shadow of microcontroller. Today's article will provide a detailed answer to the question of what are the application areas of microcontrollers.
Applications and classification of filters
1. SAW filter for GSM, CDMA, 3G and some 4G bands, i.e. 3G, 4G mobile communication technology. Mainly used in RF front ends for 2G, 3G, 4G etc. mobile phones.
New high-frequency filters help drive new breakthroughs in core technologies for the 5G industry
As a new company focusing on the research, development and production of high frequency filters, we have advanced the layout of our core technologies, hired Israeli experts in the field of communications to carry out independent research and development, and have achieved the first stage of technological breakthrough and product verification. The first batch of products to be mass-produced in June 2020 include N257, N258, N260 and N261, which are the few high-frequency filters with superior performance, high cost performance and promising applications in the global market.

Industrial switch hardware failure of port failure
Industrial switch faults can generally be divided into two categories: hardware faults and software faults. Hardware failure mainly refers to the failure of the switch power supply, backplane, modules, ports and other components, the following I will first introduce you to the problem of port failure.
