RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Rogers PCB vs. FR4 PCB - TechnoTronix

Rogers PCB vs. FR4 PCB by TechnoTronix - RF CafePCB manufacturer TechnoTronix has a blog post you might find useful entitled "Rogers PCB Vs FR4 PCB – What is the Difference?" It begins: "In the world of hi-tech gadgets, medical equipment, and Industrial Machines, the performance of any product depends mainly on the quality of its PCB design. Though there are multiple aspects to be considered while designing a PCB, our focus here is to identify the right PCB material which is also known as Substrate. Substrates are the dielectric sheets that hold the components and traces of a design. Selecting the right substrate material for a specific application is the key aspect of PCB design. To decide which substrate works best for any given application, we need to know the salient features of all the materials available on the market. The materials offered include FR1 to FR6, CEM1 to CEM5, insulated metal substrates..."

5G: Will Millimeter Waves Be High Enough?

Anatech Electronics September 2021 Newsletter - RF CafeSam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his September 2021 newsletter that features his short op−ed entitled "5G: Will Millimeter Waves Be High Enough?," where he notes the technical difficulties being experienced with components and operational environments in the mm−wave realm, and that life in the THz spectrum will be even more challenging - perhaps even impossible for general use. As we know from Friis equation, electromagnetic power levels drop proportional to the square of distance (6 dB per doubled distance), but in the THz region atmospheric absorption comes into play as physical molecules resonate at specific wavelengths, further decreasing received power...
