Microwave refers to the wavelength short language 300mm or frequency higher than 1000MHz (1GHz) electromagnetic waves, microwave printed circuit board refers to the specific microwave substrate copper-clad plate, the use of ordinary rigid printed circuit board manufacturing methods to produce a microwave substrate.

In the printed circuit board wires in the high-speed signal transmission line, currently can be divided into two categories:

A class of high-frequency signal transmission class of electronic products, this class of products is related to the radio's electromagnetic waves, it is a sinusoidal wave to transmit signals to the product, such as radar, radio and television and communications (cell phones, microwave communications, fiber optic communications, etc.);

Another category is a high-speed logic signal transmission class of electronic products, this type of product is to digital signal transmission, the same is also related to electromagnetic wave transmission of square waves, this type of product began to be mainly in computers, computers, and other applications, and now has been rapidly promoted to the application of home appliances and communications electronic products.

In recent years, high-frequency microwave printed circuit boards as electronic information and high payroll technology industry essential supporting products, has gained rapid development, the reasons for this, mainly the following points:

A. The rapid progress of the communications industry, so that the original civilian communications band appears to be very crowded, some of the original military use of high-frequency communications part of the frequency band, from 1996 onwards, and gradually let to the civilian population, so that civilian high-frequency communications to obtain a super-conventional speed of development. High-frequency communications in satellite reception, base stations, navigation, medical, transportation, warehousing and other areas of great significance.

B. High confidentiality and high transmission quality needs, so that cell phones, car phones and wireless communications to high-frequency development. At the same time, high picture quality, the requirements of light wave television transmission with very high frequency ultra-high frequency broadcast programs; high information transmission information, satellite communications, microwave communications and optical fiber communications must be high-frequency.

C. The increase in computer technology processing capacity, information storage capacity increases, the urgent need for high-speed signal transmission.

A microwave circuit assembly is a key device used to process microwave signals, which can fulfill the functions of signal amplification, filtering, mixing, frequency conversion, switching and so on. Microwave circuit components can be realized in various ways, such as microstrip lines, dielectric waveguides, microwave RF components and so on. They can be used in wireless communications, radar systems, satellite communications, navigation equipment and many other fields. In wireless communication systems, microwave circuit components can be used for signal amplification and transmission, enabling signals to be transmitted over longer distances in the system. In radar systems, microwave circuit components can be used to process radar signals for target detection and tracking. In navigation equipment, microwave circuit assemblies can be used to receive and process navigation signals to help users accurately determine their position. Microwave circuit assemblies are used in a wide range of applications and play a vital role in the performance and reliability of modern communication systems.

A microwave circuit board is a substrate used to fabricate microwave circuits on which microwave circuit assemblies can be mounted and provide connections and support. Microwave circuit boards are typically made from materials with high dielectric constants and good electrical conductivity at high frequencies to ensure their performance in high-frequency signal transmission. Manufacturing of microwave circuit boards requires highly sophisticated processes to ensure circuit stability and performance. The applications of microwave circuit boards are mainly concentrated in the field of wireless communication, such as mobile communication base stations, gigabit wireless LANs, microwave communication equipment, etc. Microwave circuit boards can improve the performance and reliability of communication equipment and provide users with a better communication experience.

In conclusion, microwave circuit components and microwave circuit boards are indispensable technologies in the field of modern communications. They have a wide range of applications and can play an important role in many fields such as wireless communications, radar systems, navigation equipment and so on.
