Polar Instruments – a specialist in tools for pcb design, fabrication and test - has announced a free webinar on pcb layer stackup design using differential pairs. Presented by signal integrity guru, ...

PCB Signal integrity & Stackup design. Ever more complex PCB designs require layer stackups to be considered even before you layout the design. As a designer there are now vast choices of base ...

Part 1 of this series described how digital signals propagate through PC boards [Refs. 1, 2, 5, 6]. In part 2, we look at specific board designs to achieve low EMI. The biggest issue I see in my ...

Eventually, almost every EE must design a PCB, which isn’t something that’s taught in school. Yet engineers, technicians, and even novice PCB designers can create high-quality PCBs for any and every ...

What is software defined radio (SDR) and how does it benefit modern communications and RF applications? RF/microwave PCB design for Radar and SDRs. Challenges of SDR PCB design and ways to overcome ...

In these example schematics 16 RJ45 ports are used. For a different number of ports the schematics can easily be modified. These schematics are provided for reference only. For any designs based on ...

A PCB transmission line design tool has been launched by Polar Instruments in an effort to speed the complex calculations needed in transmission line modelling. The Guernsey-based company said its ...

Design done, PCB laid-out and components are sourced, but the biggest challenge is yet to come getting it manufactured. David Marrakchi describes the pitfalls to avoid You just completed your last ...
