Coaxial Adapters in Demand

Comments off 284 Views0

Inter and intra series coaxial adapters and wave guide-to-coaxial adapters are some of the more common components used in RF, microwave and wireless applications. OEM’s and manufacuturing and engineering test facilities are continually required to provide temporary or permanent connections between the many coaxial and waveguide series in use. This is particularly true today where long established connector series (N, TNC, BNC, 8874, 900, SMA,e tc.,) must be mated with interfaces introduced later (3.5mm, 7/16 DIN, SSMB, SSMC, MCX, 7mm, etc.).

Recognizing this need, Coaxial Components Corp maintains a large inventory of MIDISCO and Microwave Distributors components. Some of the most common and some not so common inter and intra series coaxial and coaxial-to-wave guide adapters are available. We can also supply wave guide transitions in standard and double ridge configurations. If you have a requirement not shown in the catalog or our cross referencing tool, simply request engineering assistance through our website or call 772-287-5000.

The user should bear in mind that for best performance, the usable frequency for a given adapter is established by the operating range of the lower frequency interface on the adapter. As a guideline, a table is provided below to summarize the recommended frequency range of the more common coaxial interfaces. These guidelines represent the range for optimum performance. Most adapters are usable at higher frequencies with limitations.

Coaxicom manufactures standard and precision adapters. Standard adapters are usable to frequencies less than 12 GHz for N and TNC, or up to the recommended frequency range for the other series. Precision adapters use an “X” prefix for the part number and feature stainless steel construction for a more precise interface and an extended frequency range for the N and TNC series. In the case of precision N, TNC or SMAs interfaced with lower frequency series (ie: XBM-SM, XNF-BM etc.), the precise construction and stepped internal transition yields improved performance beyond the normal operating range of the lower frequency series.

Quantum Computing

Light the Way to Quantum Computing.

Comments off 4160 Views0

Since the 1980s, researchers have been chasing after the quantum computer. Such a computer, they believe, could transform the task of information processing by handling data in novel, unprecedented ways. Whereas current computers can only process bits that occupy one of two states (0 or 1), one promising implementation of the quantum computer would rely on arrays of atoms in quantum states, called qubits.
Thanks to the strange nature of the quantum realm, qubits can occupy both the 0 and 1 states simultaneously and can also be entangled with, and thus closely influenced by, one another. Researchers are just beginning to explore the potential processing power that these qubits could unlock.


Yet, the quantum computer has always remained just out of reach because of various fabrication difficulties. For example, researchers are able to manipulate only a small number of qubits — on a scale of tens — as opposed to the required thousands or millions.

“Across all the groups in the world that are working on quantum computing, no one has developed a way to control a very large number of qubits such that you can use them to perform an actual computation of interest,” said Jeremy Sage, a member of the technical staff in Lincoln Laboratory’s Quantum Information and Integrated Nanosystems Group. “We can’t yet do anything that is both practical and better than what a classical computer can do.”


Sage and John Chiaverini, a senior staff member in Sage’s group, lead a team that is pursuing scalability by merging photonic integrated circuits (PICs) with a quantum computing method based on charged atoms, or ions, trapped above the surface of a chip. In 2016, in collaboration with MIT, the team demonstrated that PICs could be used to effectively manipulate the quantum states of ions by performing quantum gates. A quantum gate is the quantum version of a logic gate, which processes information by producing output bits (or qubits) based on inputs and a simple set of logical rules. The Laboratory team’s most recent milestone represents a breakthrough in the precise delivery of light from lasers to the trapped ions by significantly extending the range of wavelengths over which the PICs operate.


“We use lasers to rip off electrons, cool the ions down, and perform quantum gates,” Sage said. These changes to the ions that the lasers bring about are what would power the quantum computer. The ions that the team chose to use for their research are strontium and calcium, which react to specific wavelengths of light. “It turns out we need about 12 different laser colors that range from the near-ultraviolet to the near-infrared,” Sage added.

At the moment, most researchers shine lasers through windows in vacuum chambers to

strike the ions, but this approach leaves a lot of room for error. While it’s possible to hit a few individual ions precisely, scaling to the millions introduces a high probability of hitting the wrong one.


“What we’re trying to do is deliver the light in a different way by integrating the required light-delivery optics into the chip itself,” Sage explained.


“Our PICs distribute the light from several input lasers to an array of trapped ions,” said Paul Juodawlkis, assistant leader of the Quantum Information and Integrated Nanosystems Group, who leads the integrated photonics projects at the Laboratory. “At each trapped-ion site, we use devices called vertical grating couplers to redirect the laser light out of the PIC and focus it on an individual trapped ion.”

The vertical grating couplers are periodic structures that shoot light up and out of the chip, directly aiming it at and focusing it on the trapped ion, ensuring accuracy and mitigating the risk of hitting nearby ions.
The vertical grating couplers are periodic structures that shoot light up and out of the chip, directly aiming it at and focusing it on the trapped ion, ensuring accuracy and mitigating the risk of hitting nearby ions.


Instead of shining lasers through windows, the Laboratory team uses an optical input that is plugged into the chip. The input sends the lasers through the chip to the ion of interest via paths called waveguides that are specific to each wavelength of light. When the light has reached the area on the chip that correlates with the targeted ion, it emerges through the vertical grating coupler out of the chip and triggers the ion to change states.

The PIC technology needed to create this type of chip is already used extensively in the world of tele- and data communications. Yet these PICs are traditionally made of silicon, which absorbs the wavelengths of light required to manipulate the ions rather than allowing them to propagate through the chip.


Therefore, the research team developed alternate materials: silicon nitride and alumina. This year, they demonstrated a low propagation loss, meaning a small diminishment of the light as it is sent through the chip to meet an ion, while delivering light across a wide spectrum, from the near ultraviolet to the near infrared. The team’s work is the first-ever successful demonstration of a low-loss integrated photonics platform with light delivery over such a spectrum.

“We also demonstrated that the [vertical] gratings do indeed work,” said Suraj Bramhavar, another researcher on the team. “We are now working on ways to make these gratings more efficient so that more of the light we inject into the waveguide will reach the ion.”


“I think the ion-trapping field outside of the Laboratory is paying very close attention to what we’re doing here,” Sage said. “We are one of the leaders in this effort.”The Laboratory is uniquely capable of realizing this chip because of its expertise in integrated photonics and quantum computing, and the fabrication capabilities of its Microelectronics Laboratory.


The research team will continue working on refining the chip design and fabrication process.”There are a number of challenges that need to be addressed before a large-scale, useful quantumcomputer can be realized,” Juodawlkis said. “Estimates of when useful quantum computing will be available range from 10 to 20 years. An increasing number of groups around the world are working to solve the scientific and engineering challenges, and good progress is being made.”(July 9, 2018,/, Anne McGovern | Technical Communications Group)

So how exactly will we hail a flying taxi?

NASA is working with Uber on its flying taxi’s closer than you think!

  • Uber partnered with NASA on it its flying taxi project called Uber Elevate
  • Uber will be working with NASA to figure out traffic management for flying cars
  • Uber also said that it is aiming to trial the flying taxis in Los Angeles, as well as Dubai and Dallas-Fort Worth in 2020

 Uber signed a deal with NASA Wednesday to help develop traffic systems for its flying car project which it hopes to start testing in 2020.

The ride-hailing service published details of its “on demand aviation” ambitions last year which it has called Uber Elevate.

It is now stepping up its efforts to make the project a reality. Uber said at the Web Summit tech conference in Lisbon that it signed a Space Act Agreement with NASA for the development of “unmanned traffic management.” This is NASA’s push to figure out how unmanned aerial systems (UAS), such as drones that fly at a low altitude, can operate safely.

 Uber wants to make vertical take-off and landing vehicles. That will allow their flying cars to take off and land vertically. They will fly at a low altitude.

This is the start-up’s first partnership with a U.S. federal government agency. NASA is also working with other companies to develop traffic management for these low altitude vehicles.

“UberAir will be performing far more flights on a daily basis than it has ever been done before. Doing this safely and efficiently is going to require a foundational change in airspace management technologies,” Jeff Holden, chief product officer at Uber, said in a statement on Wednesday.

“Combining Uber’s software engineering expertise with NASA’s decades of airspace experience to tackle this is a crucial step forward for Uber Elevate.”

The NASA deal is the latest in a series of partnerships Uber has struck to get UberAir — which is what the new service is called — off the ground.

Earlier this year it said it was working with authorities in Dallas-Fort Worth and Dubai to bring its flying taxis to those cities. It also signed partnerships with aircraft manufacturers and real estate companies to figure out where the take off and landing sites for the flying cars could be.

Uber said Wednesday that it also plans to trial the project in Los Angeles in 2020 along with the already announced cities. The company expects the price of a trip to be competitive with the same journey if done using UberX. It is aiming to get the flying taxi service up before the 2028 Olympics in Los Angeles.

New Weather Wizardry: Thanks to Ball Aerospace & Technologies.

Comments off 928 Views0

Weather may be global, but the impacts are local.

Looking for a more accurate weather forecast, especially after some major storms predicted for the Colorado Springs area fizzled while other fierce weather events seemed to come out of no where? A new satellite scheduled for launch in September is expected to help.

The National Oceanic and Atmospheric Administration expects the new satellite to be in operation by year’s end and help the agency’s National Weather Service unit produce more accurate mid-range forecasts, said Stephen Volz, the agency’s assistant director for its satellite and information service.

The first operation of the Joint Polar Satellite System will be to collect weather, climate and other data by year’s end and allow forecasters to generate more accurate and timely forecasts of severe weather three to seven days beforehand, Volz said while in the Springs for the 33rd annual Space Symposium, a four-day gathering of space industry officials at The Broadmoor hotel that attracts more than 11,000 people.

“While there have been flying polar satellites for 40 years, this is the first major generation upgrade since the early 1990s,” Volz said. “Every instrument on this satellite has been upgraded from the previous generation of satellites and is designed to give us better-resolution images in terms of color, spatial and other measurements and will even allow us to do cloud mapping at night, which is something we have never been able to do. It will also give us higher-precision measurements of temperature and atmospheric pressure that measure smaller areas.”

A research-and-development version of the satellite was launched in 2011 by NOAA, the Air Force and the National Aeronautics and Space Administration and has been providing data and images for about five years. The new satellite, built by Ball Aerospace & Technologies Corp in Boulder, is the first of four that are scheduled to be launched during the next 14 years and will orbit the earth from to pole-to-pole 14 times daily, providing global coverage every 12 hours. The fleet of satellites are expected to cost $20 billion during the 30-year life of the program.

The new satellites replace a fleet that is still operating but is beyond its designed life span. They will allow the agency to identify wildfires sooner and track illegal fishing at night as well as produce more accurate forecasts from more detailed data and images they generate, Volz said.

“I can’t say your weather forecast will be better tomorrow, but the models we are providing are generating increasing better forecasts and will continue to improve,” Volz said. “However the variability in weather systems has increased and severe storms have become more frequent as the atmosphere gets warmer, causing more evaporation and more moisture in the atmosphere. The fact that more severe storms will occur is a virtual certainty, but predicting where they will occur is much more difficult. Weather may be global, but the impacts are local.” (content credit: Updated: April 3, 2017 at 7:15 pm, by Wayne Heilman,, The Gazette.)
