In the high-frequency circuit, the noise of the power supply has an obvious effect on the high-frequency signal. Therefore, the first requirement is that the power supply is low noise.
The above is for everyone to share the PCB board interconnect high frequency PCB design skills, if you are familiar with these methods, you can understand the use of back copper-covered coplanar microstrip design than strip line design is more economical
PCB for high frequency, high speed transmission needs, in addition to circuit design to reduce signal interference and loss, maintain signal integrity, and PCB manufacturing to maintain in line with the design requirements, it is important to have a high
High frequency plate (high frequency microwave printed board) production problems should be paid attention to
With the continuous development of science and technology, especially information technology, the process technology of printed board production is improved accordingly to meet the needs of different users. In recent years, the development of communicatio
For high frequency applications, PCB board interconnect for high frequency PCB design techniques are
These are the high frequency PCB design tips for PCB interconnect. If you are familiar with these methods, you will understand that the coplanar microstrip design with copper cladding on the back is more economical and practical than the strip design.
a simple and applicable method is to first lay the ground wire, then place key signals such as high speed clock signals or sensitive circuits near their ground loops, and finally route other circuits. The layout of the signal line is best arranged accordi
PCB dielectric layer used for high-speed digital signal transmission, not only plays the role of insulating layer between conductors, more importantly, it plays the role of "characteristic impedance", but also affects signal transmission speed, ...
which also means that the frequency is higher and higher, the requirements of the circuit board substrate is also higher and higher.
This top view provides an example of installing a row of ground through holes in the top metal ground area on each side of the intermediate conductor. The circuit current caused by the top layer is short-circuited to the ground below.
At the same time, it should be noted that the transmission line on the PCB should not have mutations or corners, and the impedance of each point of the transmission line should be kept continuous as far as possible, otherwise there will be reflections bet
In PCB, there are only two kinds of transmission lines: strip line and microwave line. The biggest problem of transmission line is reflection, which will cause many problems.
