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
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.
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.
one is that two lines walk on the same layer (side-by-side), the other is that two lines walk on two adjacent layers (over-under). Generally, there are many ways to implement the former side-by-side.
In the actual study, we can conclude that there are four main interference, including power supply noise, transmission line interference, coupling and electromagnetic interference (EMI). Through analyzing various interference problems of high frequency PC
The reflection of the signal back to the signal source will increase the system noise, making it more difficult for the receiver to distinguish the noise from the signal,
Transmission delays on ground and interconnect lines in high-speed systems are also factors to be considered in system design.
PCB board depends on science and technology, naturally must not lag behind, so the layout of high frequency PCB has become the key point to discuss when we design PCB high frequency board.
