Crosstalk Reduction and Elimination Techniques in Altium Designer
Whether you're designing a digital board with a ton of traces, or an RF board operating at very high frequencies, any electronic device with propagating signals will experience crosstalk. It's simply a matter of whether that crosstalk is so extreme that the system fails to function, or whether crosstalk is within some acceptable limit. There is no universal level of "acceptable" crosstalk levels, but if you do find through simulation and

Today's PCB Designers Are Driving Electronics Product Design
Professional designers know they play a fundamental role in the electronics product development process. Without circuit boards, all those semiconductors are a bit meaningless and they would not be able to provide the modern experiences we all enjoy. Even as PCB designers are so critical in the product development process, they still get the short end of the stick when it comes to product development tools. PCB design software is great for

Power Integrity Analysis in Your PCB Design Software
Power integrity problems can abound in modern PCBs, especially high-speed boards that run with fast edge rates. These systems require precise design of the PDN impedance to ensure stable power is always delivered throughout the system. Without carefully considering the PDN impedance, you’re at risk of creating ripple and noise in the power distribution network when fast signals switch states. As more signals switch in large ICs, the result is the

How to Calculate a Virtual Array in MIMO Systems
RF and sensing systems that use MIMO functionality have some important design constraints concerning virtual antenna design and placement. In these systems, due to the need for finer resolution and higher transmit/receive gain, the trend has been to pack more antennas into an array for beamforming and the reception of low-level signals. There is a reason for this trend, and it relates to an important concept in antenna array systems. When
