1st Electronica Show - Americans Eye Rocky German Road

Americans Eye Rocky German Road (Electronica), February 14, 1964 Electronics Magazine - RF CafeElectronica 2018 is just a month away, it being held in Munich, Germany, on November 13th through 16th. It is held every two years at the Messe München trade-fair center. You would be forgiven for believing that because the show has always been based in Germany that it was a German nation brainchild. However, based on the article in a 1964 issue of Electronics magazine - the first year of Electronica - its progenitor was the American trade group International Electronics Association (IEA - no longer in operation). Its founders wanted to usurp France's Salle de Composants as Europe's largest components trade show. And now you know... the rest of the story, as Paul Harvey would end his broadcast. Strong opposition was provided by Germany's Central Association of the Electro-Technical Industry (ZVEI - still in operation today). In the pre-Internet world, getting the word out - especially in other countries - about a company's new product offerings  

Notable Quote by Calvin Coolidge on Persistence

Notable Quote by Calvin Coolidge on Persistence - RF Cafe"Nothing in the world can take the place of Persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan 'Press On' has solved and always will solve the problems of the human race. " - Calvin Coolidge, 30th president of the United States of America. Thanks to Ted Beck for sending it to me.

China to Launch Lunar Lighting in Outer Space

China to Launch Lunar Lighting in Outer Space - RF CafeThis headline about an artificial moon immediately smelled like fake news to me - which means a typical science-challenged reporter would buy it without question hook, line, and sinker. It doesn't occur to the writer that in order for the scheme to work, the satellite would need to be in geostationary orbit, 33,200 miles above the Earth. That's a long way with a lot of light level attenuation before even entering the densest part of the atmosphere near the surface. Scattering and dispersion would make focusing a light beam on a particular area with enough intensity to be useful would be impossible - especially in China's smog-filled cities. I've got a call in to the reporter with an offer to sell him / her the Brooklyn Bridge at a good price ...

A $25,000 Sundial from Motorola?

A $25,000 Sundial?, December 1971 Popular Electronics - RF CafeIn 1970, engineers at the Hamilton Watch Company introduced the world's first solid state electronic digital watch called the Pulsar Time Computer. It went on sale commercially two years later, just a few months after this article appeared in the December 1971 issue of Popular Electronics magazine. Motorola created this "$25,000 Sundial," which represents the research and development cost of the LED clock display that the company predicted would one day lead to an inexpensive wristwatch. Maybe they hadn't seen the The Tonight Show show where it made its debut in 1970. The Pulsar Big Time watch retailed for $295 in 1972, which in 2018 is the equivalent of $1,777 (per the BLS Inflation Calculator). That's about three times the cost of the top end Series 4 Apple Watch today, and all the Pulsar watch could do was tell time ...

Assemble Antennas with 3D Printing

Antenna Test Lab Co  - RF CafeMr. Glen Robb, owner of Antenna Test Lab, has an article in the October 2018 issue of Microwaves & RF magazine titled, "Assemble Antennas with 3D Printing. Says Rob, "Three-dimensional printers working with plastic materials can create the foundations that are then spray-painted with metallic coatings to form high-frequency RF / microwave antennas. Antennas are RF / microwave components that lend themselves to 3D printing, especially with the large volumes, miniaturization, and repeatability required for antennas in many mobile applications. Certainly, design engineers have considered the possibility of printing different types of miniature RF/microwave antennas. However, they may have wondered about how the performance of these printed antennas might compare to traditionally manufactured ..."

Don't Bypass the Hobby Shop

Don't Bypass the Hobby Shop, October 1971 Popular Electronics - RF CafeIf - and that's a big "if" - you can find a hobby shop today, it is still a great source of tools and materials for building electronics projects. Just as the convenience, vast selection of products, and competitive prices of the Internet has been killing all sorts of brick and mortar stores since the early 21st century, local hobby shops (LHS's) have all but disappeared from most towns. There are still a handful of full-featured, well-stocked hobby shops to be found, but they are rare anymore. A lot of the small hobby-type hand tools (X-acto knives and saws, Dremel tools & bits) can be bought in home improvement stores, and the large craft stores often carry balsa, aircraft plywood, poplar wood, small gauge brass and aluminum tubing and sheets, plastic models and paint, and Estes rockets ...

Radar Scores SAC Bombing Test

Radar Scores SAC Bombing Test, December 1956 Popular Electronics - RF CafeMost people have heard of the incredibly accurate Norden bombsight that was credited for revolutionizing accuracy of heavy bombers like B-17s, B-25s, and B-29s. It was an electromechanical device that took bombardier inputs of altitude, airspeed, heading, and wind speed and direction, then calculated the impact point of the bomb. An accuracy of 75 feet was claimed under ideal conditions - provided by a mechanical computing device. By 1956 when this article was published, the Norden had been replaced by radar-integrated bombing systems. Additionally, ground-based radar measurement systems were

Jeff Bezos Defends Big Tech Working with DoD

Jeff Bezos Defends Big Tech Working with DoD - RF CafeHere is why government control over the U.S. taxpayer-funded development of the Internet should not be ceded - it makes us vulnerable to the whims of a few megalomaniac chieftains. "Don't expect Amazon to follow Google's lead when it comes to working with the U.S. Department of Defense. Amazon CEO Jeff Bezos made a surprise appearance at the Wired 25 conference in San Francisco on Monday. In light of Google's decision last week to pull out of a bid for the DoD's JEDI cloud computing project, he was asked about his philosophy in regard to big tech companies working with government. 'We are going to continue to support the DoD, and I think we should,' Bezos said ..."

5G Brings New RF Challenges for Handsets

5G Brings New RF Challenges for Handsets - RF CafeOpen your smartphone and count the antennas within. They take on many form factors and are often multi-band, making it difficult for the untrained eye to discern the implementation. It is a true wonder of antenna engineering. Factor in that they have to work regardless of whether being held in a hand, pressed between a shoulder and ear, or sitting in a pocket or handbag. Genius is at work there. I remember during my reverse engineering days when there were maybe three antennas in a handset. Take a look at the block diagram in this "5G Brings New RF Challenges for Handsets" MWJ article by Ben Thomas of Qorvo and note the 8 antennas depicted. How many people can pull off such a challenge? Beyond that there is RF signal switching and isolation, analog and digital processing, filtering, AGC, ALC, and other tasks ...

Washington Newsletter - Patent Rulings

Washington Newsletter - Patent Rulings, October 4, 1965 Electronics Magazine - RF CafeJust to remind you that patent laws are continually being monkeyed with by lawmakers and challenged in court by litigants, here is a news item from a 1965 issue of Electronics magazine reporting on a Supreme Court case brought by Hazeltine Research regarding their patent application for a microwave switch. Evidently over time the Supreme Court had been raising the bar on patent filings by requiring a higher degree of uniqueness for new inventions. The 1952 U.S. Patent Act, enacted by the U.S. Congress, simplified the terms of claims for new patents, thus making them easier to obtain, but according to critics, making new patents less valuable in the process. Now (in 1965), the Supreme court was moving itself back to ward the pre-1952 criteria. Judicial activism, anyone ...

Mac's Radio Service Shop: The Not-So-Simple Sets

Mac's Radio Service Shop: The Not-So-Simple Sets, October 1953 Radio & Television News - RF CafeThe lesson learnt (or learned) by Barney in this Mac's Radio Service Shop saga is one that he has learned (or learnt) before, if you are an regular reader of the feature. As always, the story is a combination docudrama and tutorial concerned with troubleshooting, handing customers, giving air to some newfangled device, or instruction on circuit theory. Proprietor Mac McGregor is usually the teacher and Barney the pupil, but on rare occasions the roles are reversed. As you will see in this episode, radio and television set designers ginned up all kinds of ways to accomplish the same end objective - whether to avoid patent infringements or preferred exercising of creativity - and the nuances between them could cause no end of frustration to even highly trained and experienced troubleshooters ...

SAW/BAW New Market Entrants Offer New Approaches

SAW/BAW New Market Entrants Offer New Approaches - RF CafeSAW and BAW devices have been around for many decades. They have not always been inexpensive commodities during that time, however. When I first entered the defense electronics realm as an engineer in the late 1980's, a SAW filter in the 70 MHz band (common for IF's in the day) could easily cost $20 in volume quantities. They had high insertion losses and did not handle much power. Now, of course, SAW's are dirt cheap and have much better performance. This article titled, "SAW/BAW New Market Entrants Offer New Approaches," which appears in the October issue of Microwave Journal, reports on some new techniques being utilized by vendors ...
