The market demand for 5G dielectric waveguide filters is showing explosive growth
2020-11-16
Since 2020, the construction of 5G base stations in China has entered a rapid explosive period. Recently, the application for listing on the Science and Technology Innovation Board of Jiangsu Canqin Technology Co., Ltd. (hereinafter referred to as "Canqin Technology"), a domestic 5G industry chain upstream component supplier, was accepted. The company is mainly engaged in the research and development, production, and sales of microwave dielectric ceramic components, and is the world's first manufacturer to mass produce 5G dielectric waveguide filters. It is worth mentioning that Huawei, as a global leader in 5G infrastructure construction, has emerged among the company's shareholders and customers, and almost determines the company's performance growth.
Deep Analysis Filter Industry - Automated Debugging
In the development history of filters, automated debugging has always been a hot topic and a process that has not been commercialized on a large scale. In today's analysis, we first review the incomplete development history of automated debugging, and then explore the current popular automated debugging of dielectric filters.
Introduce the design scheme of the control board for the active filter cabinet
2023-03-24
The rapid development of power electronics has made various power engineering electronic systems increasingly common in industrial production, road transportation, and home use, and the harmonic current damage generated by these discrete system loads is also becoming increasingly serious. Harmonic current causes harmonic current consumption of components in the power grid, reduces the power factor of machine equipment, and even harms electrical equipment such as capacitors; Harmonic currents harm instruments and adjacent communication systems, making them unable to function properly.
Let's take a look at the design steps of the active filter cabinet together
When designing an active filter cabinet, the following design steps are generally followed. 1. Design scheme for communication Based on the needs of filter characteristics, design a certain type of farth-order transfer function, and then dissolve the n-order transfer function into multiple low-level transfer functions to multiply.
The application of active filters in airports is crucial
Flight safety has always been a top priority in airport construction. As a convenient mode of transportation for people's daily transportation, airplanes have brought diverse choices to people's daily transportation and life. However, in the low-voltage distribution system of airports, there are a large number of harmonic sources, such as airport navigation lights, DC motors, electric furnaces, rolling mills, welding machines, etc. These harmonic sources have characteristics such as large current distortion, wide harmonic spectrum range, and rapid changes in reactive power demand, Becoming the first level of flight safety. Fortunately, an active filter has appeared at a critical moment, and its role is crucial. Harmonic hazards at airports
Teach you how to choose a power filter
The function of a power filter is to suppress electromagnetic noise. The function of a power filter is to obtain a specific frequency power signal or eliminate a specific frequency power signal rope by inserting a power filter into the power system. To prevent unnecessary losses, we need to understand the use of power filters. In order to use them, we also need to know how to choose a power filter, as follows:
