Using Silicon Diodes

Using Silicon Diodes, July 1965 Popular Electronics - RF CafeI like the opening line to this 1965 article on using silicon diodes, "You can stack' em up to get all the power supply voltage you need, but you have to know how to dress 'em up." The basic rules of solid state diode implementation have not changed much since they first began gaining widespread usage. Observing peak inverse voltage (PIV), forward and leakage current, and power dissipation rating limits were and still are the primary concerns for diodes. Moving to higher frequencies, particularly in communications applications, requires attention to junction capacitance, self-generated noise, and forward and reverse recovery times. Physical size and ruggedness, temperature and humidity, and even shielding from cosmic rays can also need careful consideration ...

Ultimate All-Level Excel Bootcamp

Ultimate All-Level Excel Bootcamp - RF CafeAn ad for a self-paced course titled, "Ultimate All-Level Excel Bootcamp" appeared on the Interesting Engineering website. It is on sale for $35 (normally $249). Claims the presenters: "Manipulate data like a pro with 4 courses (69 hours of content!) for the business-minded." I would say it applies to the science- and engineering-minded as well. Although you won't need such skills to use sophisticated spreadsheets like RF Cafe's Wireless System Designer, it will help you to be capable of creating such sophistication ...

New Discovery Could Extend Limits of Moore's Law

New Discovery Could Extend Limits of Moore's Law - RF Cafe"A group of scientists from the U.S., Singapore, and China have discovered a candidate material with potential to extend the limits of Moore's Law. The research team, which worked primarily in Berkeley Lab's Molecular Foundry in association with the Department of Energy, has found a new way to add more computing power to microchips. Moore's Law is a constant companion to those working in microchip manufacturing. Simply put, Moore's Law states that the number of transistors per square inch on integrated circuits will double every year. This has ..."

The Real Inventor of Wireless

The Real Inventor of Wireless, October 1965 Popular Electronics - RF CafeCredit for being the first to accomplish any notable feat, whether in sports, medicine, science, aviation, etc., is constantly being challenged. Some contestations are worthy of consideration based on documented facts, while others can be readily dismissed as crockery. Gustave Whitehead, per anti-Wright Brothers zealots, made the first powered airplane flight. The Vikings landed in America centuries prior to Columbus - supposedly. Many stories have been written claiming that Dr. Mahlon Loomis, a dentist, beat Guglielmo Marconi in the wireless communications race by using a system of kites that took on a charge from overhead clouds. A keying device opened and closed a conductive path to ground for effecting the Morse code ...

Facebook May Have Secret Plans to Build a Satellite-Based Internet

Facebook May Have Secret Plans to Build a Satellite-Based Internet - RF Cafe"Facebook may soon join SpaceX and OneWeb in the rush to deliver Internet from orbit. A filing with the Federal Communications Commission (FCC) last week revealed details of a multi-million dollar experimental satellite from a stealthy company called PointView Tech LLC. The satellite, named Athena, will deliver data 10 times faster than SpaceX's Starlink Internet satellites, the first of which launched in February. However, PointView appears to exist only on paper. In fact, the tiny company seems to be a new subsidiary of Facebook, formed last year to keep secret the social media giant's ..."

Mac's Service Shop: Getting the Most from Your Service Dollars

Mac's Service Shop: Getting the Most from Your Service Dollars, February 1972 Popular Electronics - RF CafeAlthough not entirely necessary to enjoy this story, it occurs to me that many people reading it might not know how to compare the size of a "man cookie" to a 45 rpm record - or for that matter even know what a record is (other than a unit of database storage). A 45 rpm record (single) is 7 inches in diameter, as opposed to a 33-1/3 rpm (LP 'long playing' album) which is 12 inches. Now you can get past the opening paragraph and glean the advice offered by electronic repair shop owner Mac McGregor regarding seeking out repair services. It applies to automobiles as well as electronics. The really interesting point I found, however, was his quoting of a 1970 statistic claiming that by 1980 the U.S. would employ more service employees than manufacturing ...

Antenna Placement Does Make a Difference!

Antenna Placement Does Make a Difference!, November 1966 Popular Electronics - RF CafeThis article in a 1966 issue of Popular Electronics presents a surprising and almost counterintuitive result when measuring the radiation pattern of a CB-type antenna mounted at various points on a car. If you were asked to make a rough sketch of the radiation pattern when the antenna is mounted in the center of the roof, center of the trunk, and on each of the front and rear and left and right fenders, would yours look like those in the article (assuming an all-metal car)? Today, there are many electromagnetic radiation pattern simulators available to help predict antenna performance in just about ...

Physicists Find Signs of a Time Crystal

Physicists Find Signs of a Time Crystal - RF Cafe"Yale physicists have uncovered hints of a time crystal—a form of matter that "ticks" when exposed to an electromagnetic pulse—in the last place they expected: a crystal you might find in a child's toy. The discovery means there are now new puzzles to solve, in terms of how time crystals form in the first place. Ordinary crystals such as salt or quartz are examples of three-dimensional, ordered spatial crystals. Their atoms are arranged in a repeating system, something scientists have known for a ..."

Bathtub Caulk - A Miracle on the Electronics Bench

Bathtub Caulk - A Miracle on the Electronics Bench, January 1965 Popular Electronics - RF CafeAs far back as 1966 electronics hobbyists knew that silicon bathtub caulk was an excellent flexible insulator for electronics. It originally went by the name "Silastic," which is a portmanteau of "silicone" and "plastic," and is a type of RTV (room temperature vulcanizing) compound. It has a typical voltage withstanding of over 400 V/mil, or 400 kV/inch, which is why it is used extensively on high voltage connections. Dow Corning, its inventor, still sells various compounds of Silastic both as an insulator and as a molding compound. I used it at Westinghouse Electric in the 1980's to seal metal molds for overmolding towed sonar transducer arrays ...

San Francisco Circuits Announces Fine-Pitch PCB Assembly Capabilities

San Francisco Circuits Announces Fine-Pitch PCB Assembly Capabilities - RF CafeSan Francisco Circuits announces new fine-pitch PCB assembly capabilities and services for high density applications. "Fine pitch" circuits can be defined as circuit boards with a significantly high number of components per square inch. That is, the components are extremely close together and the board’s design rules are pushing the limits of PCB fabrication tolerances. These can also be referred to as "high-density PCB assembly." The launch of these capabilities was in response to increased demand for fine-pitch PCBA at high volume production and prototype levels ...

Seven decades had passed since then. A similar article could be written today, five decades hence, about today's knowledge and technology compared to that of the mid 1960's. For instance, DNA had not yet been sequenced, 3D printing did not exist, Al Gore had not invented the Internet, MRI machines were not available, there were no cellphones, PC's were only a dream, booster rockets could not land self-powered for re-use, TV's used CRT's ...
