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...

Axiom Blog: Test Equipment Are Investments in Low Carbon Footprint

Axiom Blog: Test Equipment Are Investments in Low Carbon Footprint - RF CafeAxiom Test Equipment, an electronic test equipment rental and sales company, has published a new blog post that aims at informing people about the importance of carbon neutrality and about the different test equipment that support it with the help of regenerative energy. It suggests a thinking-out-of-the-box approach regarding how "test applications can strive for low carbon footprints by characterizing the quality of a device under test (DUT) that supports carbon neutrality, such as regenerative energy in an EV's charging system. Efficient use of energy is possible by feeding power generated by a DUT during the measurements back to the power grid, rather than dissipating the energy as heat lost to the environment." On a single DUT (Device Under Test) basis that might seem insignificant, but when hundreds of millions of vehicles are being tested of time, the energy saved can be enormous...

CMT Webinar: Introduction to Antenna Aperture

Copper Mountain Technologies Webinar: Introduction to Antenna Aperture - RF CafeCopper Mountain Technologies will be presenting a webinar entitled "Introduction to Antenna Aperture," hosted by none other than Robert Zavrel (W7SX), author of "Antenna Physics: An Introduction." It begins at 2:00 pm EST on Tuesday, April 27th. Robert is an accomplished RF Engineering Executive with 30 years of applicable experience and a verifiable consistent record delivering technical innovation, streamlined operations, increased productivity, and exceptional leadership and mentoring. The concept of antenna aperture is perhaps the most important antenna specification that is largely ignored by amateur texts. Many commonly published equations for radio engineers and amateurs alike rely upon antenna equations that employ aperture but never explain the fundamentals, they simply give the equations and leave it at that. The purpose of this brief overview is to explain the concept and relate it to why we should care. Virtually all advanced texts on antenna theory explain aperture in detail since their goal is to provide deep understanding of the subject This is an attempt to provide an empirical fundamental understanding...
