electronic microwave circuit boardManufacturers believe that PCB design principles involve many aspects, including basic principles, anti-interference, electromagnetic compatibility, safety protection and so on. For these aspects, especially in high-frequency circuits (especially microwave-grade high-frequency circuit boards), the lack of related concepts often leads to the failure of the entire research and development. Many people still stay on the basis of "connecting electrical principles and conductors to play a predetermined role", and even think that "PCB design belongs to the consideration of structure, process and improving production efficiency".
electronic microwave circuit boardManufacturers believe that digital circuits with its strong anti-interference, error detection and correction capabilities, can be arbitrarily constructed a variety of intelligent links to ensure the normal function of the circuit. An ordinary digital application circuit, high additional configuration of various "normal" links, is obviously a pioneering work without product concept. But it often leads to a series of product problems that are considered "not worth. The reason is that this functional link, which is not worthy of reliability guarantee from the perspective of product engineering, should be based on the working mechanism of the digital circuit itself, and the wrong structure in the circuit design (including PCB design) leads to the circuit in an unstable state. This unstable state leads to similar problems in high-frequency circuit boards, which belong to the basic application under the same concept.
Electronic microwave circuit board manufacturers believe that in digital circuits, there are two aspects worth taking seriously:
1. Electronic microwave circuit board manufacturers believe that the working speed of digital circuits is developing towards unprecedented high-frequency circuit board design (for example, the current CPU frequency has reached more than 2GHz, far exceeding the lower limit of the microwave frequency band). Although the reliability guarantee functions of the relevant devices are synchronized, they are based on the characteristics of the internal and typical external signals of the device.
Electronic microwave circuit board manufacturers believe that the digital signal itself is a broad-spectrum signal. According to the result of the Fourier function, it contains rich high-frequency components, so the high-frequency components of digital signals are fully considered in the design of digital integrated circuits. However, in addition to the digital integrated circuit, if the signal transition area within and between the various functional links is arbitrary, it will cause a series of problems. Especially digital and high frequency circuit board mixed circuit occasions.
Electronic microwave circuit board manufacturers believe that for the design of high-frequency circuits, there is a good CAD software, its powerful function is enough to overcome the lack of people in the design experience, as well as cumbersome parameter retrieval and calculation. With a powerful network analyzer, it is reasonable to say that people with a little experience can also complete RF components with good quality and quantity. However, this is not the case.
electronic microwave circuit boardManufacturers believe that CAD software relies on powerful library functions, including component parameters and basic performance indicators provided by most radio equipment manufacturers in the world. Many RF engineers mistakenly believe that as long as they use tool software to design, there will be no big problems. However, the actual result is always the opposite of the wish. The reason is that they gave up the flexible application of the basic concepts of high-frequency circuit design and the accumulation of experience in the application of basic design principles under the wrong understanding. As a result, basic application errors often occur in the application of software tools. RF circuit design CAD software is a transparent visualization software, and its various high-frequency basic configuration model libraries are used to simulate the actual circuit working state.
