A colleague, Mike Stasiowski, and I came up with this quick GHz wavelength formula while designing quad ridge circular polarized jamming antennas for the military when working at Nurad. The textbook formula (wavelength = c/f) where: c = the speed of light 3.00×108 m/s, and f = frequency in Hz, was cumbersome at times to calculate, then convert, to inches for practical … [Read more...]

Shielding Design Flow Chart
The flow chart in Table 1 will assist the designer in selecting the appropriate shielding options necessary to meet their shielding and environmental requirements. The shielding requirement flow chart begins by identifying the type of NEMA or IP enclosure based on the intended environment (indoor/outdoor, military/commercial, marine or land/desert). Then, using the resulting … [Read more...]

Can 5G Sites Be Good Neighbors?
Baseball Hall of Famer Yogi Berra was notable for his skill on the field and was equally notable for many of his quotes. “Yogi-isms” were things he often said that were both amusing and insightful. Referring to a popular restaurant, he said, “Nobody goes there anymore; it’s too crowded.” Sounds like a contradiction, but it’s easy to follow his meaning. Customers chose not to … [Read more...]
Drag Races, a Cashless Society, and the Threat of EMP
About a month ago, my 12-year-old son and I made his first-ever trip to the NHRA Drag Races near our home. It’s something that I always did with my dad, and I have looked forward to taking him ever since he was born. It’s a typical father-and-son day, wrought with loud, fast cars, terrible food, and the occasional waft of nitromethane fuel in the air. The drive is about … [Read more...]

When Do You Need Low-Dk PCB Laminates?
Designers looking to build more advanced systems operating at higher data rates and bandwidths tend to rely on materials with low dielectric constant values, i.e., low-Dk materials. It has gotten to the point where every high-speed PCB design guide implies that high-speed and RF designs will not function without a low-Dk material like Rogers or Arlon. The reality is that … [Read more...]
