Anatech Electronics, a manufacturer of RF and microwave filters, has published its December newsletter. In it, Sam Benzacar writes his annual "RF and Microwave: The Year in Review." He addresses the emerging technologies that are actually making 5G a reality in spite of the seemingly insurmountable obstacles presented by the realities of physics. We've been there before with other newfangled technologies; i.e., Bluetooth. Sam has a very quotable line regarding the driverless vehicle craze, "And for laughs, there's always driverless vehicles, a goal driven (it seems to me) by people who either don't drive or hate to." Maybe, just maybe, he will be writing in his 2028 year-in-review about the unexpected success of driverless vehicles. "The future" always manages to get here, even if a little late. There are also a few news items relevant to Anatech Electronics' business (that would be RF filters).

RF and Microwave: The Year in Review

By Sam Benzacar

For the last nine years in this column I've looked back on how the RF and microwave industry fared in the previous 12 months. It's more than an exercise; it helps me (and hopefully you as well) consider what the next year might bring. So, let's look back on the year that was from the unique perspective of the microwave industry, and the obvious first place to start is the fifth generation of cellular.

Two years ago, accomplishing all or even half of what had been promised for 5G seemed to me unlikely at best and probably impossible in some cases. Taken at face value, operation at 60 GHz, round-trip latency of 1 ms, download speeds of 1 Gb/s, and other goals seemed to defy logic if not the laws of physics. But the more you learn about the truly massive global efforts to make 5G a reality, the more plausible these goals become, perhaps not all of them right away, but surely in the following years.

For example, operating at millimeter-wave frequencies of 28 GHz and above is an enormous challenge, which is why few commercial applications have ever used this spectrum. In fact, it's likely no one would be trying it today if not for the allure of virtually unlimited bandwidth. Nevertheless, bandwidth is the core requirement for cellular to grow in the decades to come and millimeter wavelengths, especially those above about 40 GHz, are basically vacant. So, there's no time like the present to take a deep breath and dig in.

Last year, Nokia, Huawei, Samsung, and many others demonstrated that communication at these wavelengths is indeed possible given the proper resources. The U.S. also took a major leap forward this year in establishing the nationwide public safety broadband system administered by FirstNet, as AT&T was awarded the contract to build it, and states began opting in or in some cases out if they chose an alternative approach. It's taken more than a decade to reach this point, and huge obstacles were surmounted along the way, but the network or at least most of it will be built by the end of the decade.

It's also arguable that 2017 was the year that IoT became more than a grandiose plan to connect everything connectable, primarily by wireless means. Like 5G, the promises for IoT have been so all-encompassing that the acronym has earned a long-term place on Gartner's "Hype Cycle for Emerging Technologies" list. It's still there, and isn't likely to disappear, because like 5G IoT has so much momentum and so many stakeholders that failure isn't an option, at least in the long term. In the meantime, it's going to be a rough ride.

And for laughs, there's always driverless vehicles, a goal driven (it seems to me) by people who either don't drive or hate to. The technical challenges to make autonomous vehicles possible are truly immense, and communication between vehicles and between vehicles and external sensors is a hurdle that finally was addressed in a realistic fashion this year. That is, the 1999 decision to use 5.9 GHz for this purpose (Dedicated Short-Range Communications, or DSRC) is no longer the best solution.

The cellular industry is making its case for LTE and later 5G as the solution, as they might be expected to, but it makes sense. These developments are just a few of those with potential impact on the RF and microwave industry that occurred this year. Overall, it was a good year for the industry, especially because 5G, IoT, FirstNet, and others are new markets that are just emerging and will (or should) be new revenue sources for many years.

So, on behalf of everyone at Anatech Electronics, enjoy the holiday season and the coming new year!

What's News...

Pet Face Recognition for Pets?

Pet Face Recognition for Pets? - RF CafeMicrosoft recently showed off a new feature in Windows 10 IoT Core, the subset of Windows dedicated to smaller devices, that can recognize a pet when it attempts to enter a "pet door" in a home. The system uses sensors and motors to automate the process of identifying a pet, after which a motion sensor is triggered that activates a webcam. Capturing a few frames of the animal, images are processed using a classifier, granting rejecting an animal's access. The process takes a few seconds.


Microwave Energy, Missile Destroyer?

Microwave Energy, Missile Destroyer? - RF CafeHigh-power microwave directed energy weapons are back on the radar thanks to North Korea's expanding ballistic missile capabilities. With enough radiated power, the story goes, it might be possible to defeat missiles on the launch pad or just after launch not by blowing them up but by disabling their electronics using massive amounts of RF power. An AIM-120 AMRAAM missile launched by an F-35 fighter might be an option, as could whatever finally emerges from the Counter-Electronics High-Power Advanced Microwave Project (CHAMP) program in development for years by Boeing and the Air Force Research Laboratory. Details like power output are closely held.


Sprint Hits 140 Mb/s Using License Assisted Access

Sprint Hits 140 Mb/s Using License Assisted Access - RF CafeSprint has demonstrated its ability to achieve up to 140 Mb/s using Licensed Assisted Access (LAA) in a modest 5-MHz channel. The carrier is offering a small cell from SpiderCloud for is 1.9-GHz spectrum with 2.5 GHz support coming next year. The goal is to make LTE small cell deployment as easy as Wi-Fi. It uses a "listen-before-talk" approach to prevent interference. The SpiderCloud system employs self-organizing/self-optimizing network (SON) technology to adapt to changing signal density conditions as well as an integrated W-Fi chipset to sniff the Wi-Fi environment. LAA pairs licensed and unlicensed spectrum (potentially including the new 3.5 GHz CBRS spectrum in the U.S.).

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
