One of the major
advantages of the age of powerful personal computers - be they in the form of desktop
systems, tablets, or smartphone apps - is that for most
computation-intensive tasks there only needs to be one or maybe at most a few
people smart enough to know how to do it. Everyone else who has to perform the task
just needs to be able to input the proper parameters to ensure a useful output. That
is a significant statement, because in the days before ubiquitous computer
availability and incredible computing power, highly capable engineers, scientists,
analysts, and mathematicians either had to be on staff or an expert external resource
was used for difficult and/or time-intensive tasks. Over time, fewer and fewer people
are needed to produce very precise and reliable results. In many ways, other than the
creative intuition involved in concept, creation, and execution, a large part of the
product design and planning phases have been automated ...

Longtime RF Cafe visitor, electrical engineer, and occasional contributor Alan Dewey
sent me a note yesterday saying a book for which he helped provide a large amount of
research data has been published by authors Iain Dey and Douglas Buck. "The Cryotron Files:
How the Inventor of the Microchip Put Himself in the KGB's Sights," is an extensive
delve into the background of Dr. Dudley Allen Buck, whose son, Douglas, conducted
an extensive investigation into his father's mysterious death that happened to coincide
with the death of his colleague and two other scientists just days after being visited
by Soviet computer experts. Dr. Buck was a superconductivity researcher during his
short, highly productive life. A cryotron, BTW, is a superconducting switch that would
make for very low power supercomputers if it could be made practical in IC form ...
MECA Electronics has created an app note titled
"Isolator/Circulator Basics" on their website blog. "An RF isolator
is a two-port ferromagnetic passive device which is used to protect other RF components
from excessive signal reflection. Isolators are common place in laboratory applications
to separate a device under test (DUT) from sensitive signal sources. An RF circulator
is a three-port ferromagnetic passive device used to control the direction of signal
flow in a circuit and is a very effective, low-cost alternative to expensive cavity duplexers
in base station and in-building mesh networks. Examples of both applications will be
covered later in this article. " You can find app notes for power coupler, dividers,
and combiners, passive intermodulation products, hybrid couplers, and more on MECA Electronics'
website blog ...
In 1960, futurists were predicting that within
10 years it would be possible to beam television signals between continents and directly
into homes. It was the eve of Project Echo, which boosted a 100-foot-diameter inflatable
metallized plastic ball into low Earth orbit to reflect signals efficiently back through
the atmosphere. Engineers and scientists were already planning the next best thing -
a satellite that not only reflected, but also amplified, possibly frequency converted,
and would even steer signals that impinge upon it. Envisioned in this article is hundreds
of satellites being available for relaying signals between all regions of the Earth on
then-standard VHF channels. We now have successful
satellite television systems, but they operate at Ku-band due to bandwidth
requirements and need special converters to interface with a television ...

"Intel announced a new
5G chip for smartphones and other gadgets that the company will release
next year. The company said it expects the chip, which supports speeds up to 6 Gbps,
to ship in commercial devices starting in 2020. That timeframe is notable considering
Fast Company reported that Apple will launch a 5G iPhone with Intel's 5G chip in 2020.
The Fast Company report even cited the model number of Intel's chip - 8161 - which is
just one digit off from the name of Intel's chip announced today, the XMM 8160 5G modem.
Intel's Cormac Conroy, VP and GM of the company's communication and devices group, declined

1933 "Century of Progress" World's Fair, held in Chicago, was a big
deal on many fronts. Life in America and around the world was changing rapidly due to
the widespread introduction into homes a decade earlier of electrical and telephone service,
indoor plumbing, and associated appliances. The state of the art was a modern wonder.
Transportation had been made affordable to many families, and leisure time was becoming
more abundant. If it were not for the advent of the stock market crash in 1929, economies
would be thriving because there was so much cool stuff to be had. Many people had taken
up the hobby and/or profession of wireless communications, so a display was included
on the fairgrounds for the craft. An interesting consequence of a combination of noisy
(electrically) electromechanical wonders being promoted
and the desire to demonstrate working amateur radio equipment was a necessity to locate
the two as far apart as possible...

Remember when the first manned spacecraft transported
astronauts to Mars and then back to Earth in the 1970s - a 13-month round trip? In
the mid-1960s, Electronics magazine reported on the preparations being made
by NASA for Mars travel at the same time they were busy preparing the Apollo mission
to the moon. The world's first manned orbit (Apollo 8) of the moon didn't happen
until in December 1968, a mere seven months before the historic July 1969 Apollo 11
moon landing*, but NASA was wasting no time planning for the next big thing. Of course
you know to date we never have made it to Mars with a manned spacecraft, but the headlines
are still filled with "any day now" projections by SpaceX's Elon Musk (whom I like) and
his contemporaries. Sure, I would love to be alive to witness a manned mission to Mars,
but I'd settle ...

"It wasn't that long ago that frequencies above
between 5 and 10 GHz were considered impractical for mass-market applications due to
challenges with requisite components, materials, layout, and production tolerances. While
these frequencies have been widely used for mil/aero, scientific, and other advanced
applications, they were viewed as being at the 'outer limits' of practicality for consumer and most industrial situations
(although some 24-GHz sensing has been in use for applications like industrial fluid-level
measurement). This scenario at the higher range of gigahertz frequencies has changed
dramatically due to advances ..."

"Canadian researchers use scissors and glue to
transform RFID tag into device that can sense its environment While smart devices
are proliferating in the industrial and domestic environments, concerns remain that they
will not be sustainable unless their need for batteries and/or charging is removed. Researchers
at the University of Waterloo in Ontario, Canada, are claiming a major advance in this
area through making simple modifications to a radio frequency identification (RFID) tag,
a battery-free device used to make objects machine-readable for the location and identification,
and which are increasingly ubiquitous in common objects ..."

"Miniaturized semiconductor devices with energy
harvesting features have paved the way to wearable technologies and sensors. Although
thermoelectric systems have attractive features in this context,
the ability to maintain large temperature differences across device terminals remains
increasingly difficult to achieve with accelerated trends in device miniaturization.
As a result, a group of scientists in applied sciences and engineering has developed
and demonstrated a proposal on an architectural solution to the problem in which engineered
thin-film active materials are integrated into flexible three-dimensional (3-D) forms.
The approach enabled efficient thermal impedance matching ..."
"Rice University scientists have built a better
epoxy for electronic applications. Epoxy combined with ultrastiff
graphene foam invented in the Rice lab of chemist James Tour is substantially
tougher than pure epoxy and far more conductive than other epoxy composites while retaining
the material's low density. It could improve upon epoxies in current use that weaken
the material's structure with the addition of conductive fillers. The new material is
detailed in the American Chemical Society journal ACS Nano. By itself, epoxy is an insulator,
and is commonly used in coatings, adhesives, electronics, industrial tooling and structural
composites. Metal or carbon fillers are often added for applications where conductivity
is desired, like electromagnetic shielding ..."

"As the FCC digs into its latest spectrum auction,
and as T-Mobile prepares to light up 5G services on its
600 MHz spectrum, the time is right to take stock of the nation's
600 MHz landscape. The FCC's 600 MHz incentive auction of TV broadcasters' unwanted spectrum
was a noteworthy event. It was the culmination of years of work by officials at the FCC
- it initially arose from Congress' National Broadband Plan in 2010 - and it featured
'beachfront' low-band spectrum ideal for long-distance connections. Further, the auction
itself sported a unique 'reverse' auction that paid TV broadcasters for their unwanted
spectrum licenses, and then made that spectrum available to wireless carriers and others
through a traditional 'forward' auction ..."
