electronic microwave circuit boardManufacturers believe that the so-called microwave circuit usually refers to the circuit with a wavelength of 10m ~ 1cm (30MHz ~ 30GHz) in the working frequency band. In addition, there are millimeter wave (30~300 GHz) and submillimeter wave (150~3000 GHz). In practice, a circuit having a high operating frequency is often referred to as a "high frequency circuit" or a "radio frequency (RF) circuit" or the like.
electronic microwave circuit boardManufacturers believe that due to the high operating frequency of microwave circuits, microwave circuits are different and unique from ordinary low-frequency circuits in terms of materials, structure, circuit forms, components, and design methods. As an independent professional field, microwave circuit technology has developed very mature in theory, materials, technology, components, design technology and so on, and its application fields are more and more extensive.
Electronic microwave circuit board manufacturers believeWith the rapid development of large-scale integrated circuit technology, the working speed of the chip has exceeded1GHz. In the design of chips, packages and application circuits of these high-speed circuits, some microwave circuit design techniques are fully applied. In the past, the boundaries between traditional low-frequency circuits and digital circuits and microwave circuits will become more and more blurred, and there will be more and more mutual reference and comprehensive technology applications.
Electronic microwave circuit board manufacturers 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-level high-frequency circuits), the lack of related concepts often leads to the failure of the entire project. 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". Many professional RF engineers do not fully realize that this link should be the special focus of the whole design work, and mistakenly spend their energy on the selection of high-performance components, resulting in a substantial increase in cost but little improvement in performance.
Electronic microwave circuit board manufacturers believe that digital circuits, with their strong anti-interference, error detection and correction capabilities, can arbitrarily construct various 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 circuit design (including PCBdesign)The incorrect construction in causes the circuit to be in an unstable state.
