About RF Cafe

    BSEE - KB3UON

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 tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Windfreak App Note: Testing RF Generators for Reliability

Windfreak App Note: Testing RF Generators for Reliability - RF CafeDavid Goins, founder of and chief engineer for Windfreak Technologies, has written a number of application notes pertaining to the specification and testing of RF and microwave frequency signal generators. Most of the articles include features and applications for Windfreak Technologies products, but the concepts are universally applicable. His latest, "Testing RF Generators for Reliability" is featured here. It begins: "We pride ourselves in designing, building, and selling high value radio frequency products that are thoroughly evaluated and tested. All of our products go through rigorous testing before releasing to our customers. Our devices have proven to be very reliable. In rare cases, we have had a product come back for repair caused by output amplifier failures. In this post, we explain the testing process we go through to ensure our high-quality products and the two reasons for output amplifier failures..."

Anatech Electronics January 2022 Newsletter

Anatech Electronics January 2022 Newsletter - RF CafeSam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his January 2022 newsletter that features his short op−ed entitled "AM Radio Is Not Dead. Yet.," where he surveys the current AM landscape including listener demographics, current technology, and FCC regulations. As a lifelong AM listener myself, I definitely fit into the age-60-ish typical adherent, and talk radio is my primary daytime programming preference. In the evenings I switch over to FM music stations. Over the air broadcasting is also still my choice, and my radios typically use dials connected to variable capacitors - no electronic pushbutton tuning. Most AM and FM stations also offer Internet-based access, where all of the static, fading, and other forms of signal degradation are eliminated. Truthfully, those "annoyances" are nostalgia to my 64-year-old ears, so I don't mind needing to occasionally reorient an antenna or tweak the dial a bit for good reception. Sam believes - probably correctly - that AM radio will be gone by the end of this decade. The way things are going, I'll be gone by then as well, so hopefully AM broadcasts will hold on just a little while longer...

Make Older Gear Work When New Test Equipment Cannot Be Found

Axiom Test Equipment Blog: Make Older Gear Work When New Test Equipment Cannot Be Found - RF CafeAxiom Test Equipment, an electronic test equipment rental and sales company has published a very unique and helpful new blog post entitled "Make Older Gear Work When New Test Equipment Cannot Be Found." Since the beginning of the COVID plandemic two years ago, everything from housing to cars to food to medical care has been increasingly difficult and expensive. Test Equipment and other electronics items have not been spared during this time. This article informs people on the different alternatives available to them due to today's global supply chain challenges that prevents them from finding the specific unit they're looking for. Shortages have led to a great deal of creativity in electronic design and manufacturing when a part cannot be found. Amplifier designers, for example, may have to change transistors and integrated circuits (ICs) and with them the circuit materials that best suit the amplifier. If it is possible to modify an electronic product with available components..
