RF PCB Design Tips and Tricks

May 8, 2025 | Cherie Litson, EPTAC MIT CID/CID+

There are many great books, videos, and information online about designing PCBs for RF circuits. A few of my favorite RF sources are Hans Rosenberg, Stephen Chavez, and Rick Hartley, but there are many more. These PCB design engineers have a very good perspective on what it takes to take an RF design from schematic concept to PCB layout.

The Right Blend: Mixed Wireless Technologies

May 8, 2025 | Kirsten Zima, Siemens EDA

A common trend recently is to employ as many radios as possible on a single PCB. With the increase of wireless standards and the downscaling of PCB size, it can be difficult to know what the most critical design parameters are to focus on. In this article, we’ll discuss the most important considerations to make when designing with mixed wireless technologies, such as Bluetooth, GPS, and Wi-Fi, on a single PCB. These considerations include antennas, frequencies, FCC compliance, shielding, and layout with and without transition vias.
