Electronics in Israel

Electronics in Israel, January 17, 1964 Electronics Magazine - RF CafeOnce World War II and the Korean War were through consuming a large percentage of the world's material and labor resources, technology focus shifted largely toward inventing and manufacturing consumer goods. It was a period similar to the Roaring Twenties, after World War I where innovation and high employment fueled good times for a lot of the population. Creature comforts like indoor plumbing, refrigerators, electric toasters and can openers, radio, affordable automobiles, were appearing in the majority of homes. Unfortunately, not all countries enjoyed the upturn during those eras, usually because of continued war and/or oppressive Communist / Socialist / Marxist regimes. Israel did not formally become a country again until 1948, having been ruled ...

Low-Friction Interface Has Potential for Wear Reduction

Low-Friction Interface Has Potential for Wear Reduction - RF Cafe"Discovery may herald high-performance computer hard disks where lack of friction enables greater data storage. It has long been known that layered solid materials, particularly graphite, can act as lubricants. A joint project between Tel Aviv and Tsinghua Universities has now found that the interface between graphite and a two-dimensional material, hexagonal boron nitride, exhibits a property known as superlubricity where friction between two surfaces virtually disappears altogether. 'Superlubricity is a highly intriguing physical phenomenon, a state of practically zero or ultra-low friction between two contacting surfaces,' said Prof Oded Hod ..."

Fairchild Semiconductor Advertisement

Fairchild Semiconductor Ad, December 13, 1965 Electronics Magazine - RF CafeMaybe at one time I knew this, but the claim by Fairchild Semiconductor in this 1965 Electronics magazine advertisement took me by surprise. They claim to have invented the dual-inline-package (DIP) format. According to Wikipedia, a trio of chaps - Don Forbes, Rex Rice and Bryant Rogers - all Fairchild engineers, developed the DIP package in 1964, a year prior to the ad. Previously, a round can designated TO# (Transistor Outline) with # (number) leads around the perimeter was used for integrated circuits, but as the I/O pin count increased, that form factor became unwieldy. An extensive search for a patent on the DIP, assigned to Fairchild and/or the three inventors, did not turn up anything ...

Reusable Lab-on-a-Chip Uses Acoustic Waves to Manipulate Fluid Droplets

Reusable Lab-on-a-Chip Uses Acoustic Waves to Manipulate Fluid Droplets - RF Cafe"Researchers in the U.S. have developed a way to manipulate and mix droplets of fluids by having them surf on acoustic waves in oil. The group, from Duke University in North Carolina, claims that the technology could form the basis of a reusable and programmable biomedical chip for applications ranging from diagnostics to laboratory-based research. So-called lab-on-a-chip systems have played an increasingly important role in the biomedical and pharmaceutical sectors, but because these devices rely on solid surfaces their application has been hindered by problems related to surface absorption ..."

TV X-Rays Are Back

TV X-Rays Are Back, June 1969 Radio-Electronics - RF CafeColor television was a big hit with homeowners and was adopted fairly rapidly in the 1960s even considering the relatively high cost and low number of network color broadcasts in the beginning years. The enthusiasm underwent a severe reduction when word got out that large doses of x−rays were streaming out of the front of the CRT for sets that did not take precautions to prevent it (which was the majority of sets initially). The major cause was extremely high voltages applied between the electron gun and phosphorescent raster grid - in the neighborhood of 35 kV or more - when the high voltage regulator circuit malfunctioned. Note that even when everything was working properly ...

New Classic, Highly Informative Watkins-Johnson Tech-Notes Added

New Classic, Highly Informative Watkins-Johnson Tech-Notes Added - RF CafeBelieve it or not, there was a time when the Internet did not exist and getting quality information could be difficult. Offices, cubicles, laboratories, company technical libraries, even hallways, were piled high with reference books, magazines, component books, applications notes, datasheets, white papers, and every other form of information that might be useful. Watkins-Johnson Tech-Notes were particularly notable for their practical design and application content. Thanks to Mr. Larry Jugler for providing these three new Watkins-Johnson Tech-Notes for adding to my collection of PDF files:

All-Transistor TV Receiver Shown by RCA

All-Transistor TV Receiver Shown by RCA, February 1953 Radio-Electronics - RF CafeThis news tidbit appeared in a 1953 issue of Radio-Electronics along with an editorial by Hugo Gernsback titled "Transistor Transition." RCA had just developed its first fully solid state - except for the cathode ray tube (CRT) - television. Note that at the time the CRT was still often referred to as a kinescope. In fact, the word "kinescope" was coined and trademarked by RCA, so they had a vested interest in perpetuating its usage. Jerry Herzog, shown in the photo, was one of the engineers responsible for the design and construction of the television ...

Are Telcos Ready for Smart Home $11.2B Opportunity?

Are Telcos Ready for Smart Home $11.2B Opportunity? - RF Cafe"ABI Research estimates the smart home segment could potentially be worth in the region of $11.2B by 2022, but the diversification question still remains for the telcos. The smart home is a concept which has been on the horizon for some time, we've been debating the merits of talking fridges for years, but until recently it has perhaps been little more than a gimmick. The advantages of the expensive upgrades were limited, and in all honesty, there seem like little point in connecting your toilet to the internet. That said, during the last 12-18 months applications and services have started to appear to make the prospect genuinely..."

Transistor Transition (Hugo Gernsback Editorial)

Transistor Transition (Editorial), February 1953 Radio-Electronics - RF CafeHugo Gernsback was well-known not just for his technical prowess, but for an uncanny ability to predict future developments in electronics, transportation, and production methods. Barely three years had passed since Messrs. Bardeen, Shockley, and Brattain, announced their invention of the transistor when this editorial titled, "Transistor Transition" appeared in Radio-Electronics magazine. Gernsback mentions the concept of "appliqued circuits" (i.e., printed circuits) and "roll-up display" transistor picture tubes (i.e., flexible displays), and "pocket radios" that can be held up to the ear. Production prices for transistors at the time were about $8 apiece, which is the inflation-adjusted equivalent of $76 in 2018. At that price point, who could blame the pro-tube, never-transistor crowd from denying the possibility of transistors ever replacing tubes ...

Please Welcome Rohde & Schwarz as a New Banner Advertiser!

Rohde & Schwarz New Sponsor - RF CafePlease welcome Rohde & Schwarz as RF Cafe's newest Banner Advertiser in a 160x600−px slot! R&S has been a long-time supporter. Dr. Lothar Rohde and Dr. Hermann Schwarz founded the company Munich, Germany, in 1933. Per a Wikipedia entry, R&S received a electronics equipment depot maintenance contract in 1945 from the U.S. Army, which might be their first presence here in the U.S., providing serious competition to Hewlett Packard. I found this Rohde & Schwarz ad in a 1965 issue of Electronics magazine. Rohde & Schwarz is now a premier player in the communications test equipment realm. Lab benches and production test stations have taken on a noticeably blue hue thanks to all the R&S equipment in use ...
