Extend Range, Throughput Using BAW Filters

En julio 29, 2020 en All, IoT, RF por Jon Gabay

As more airwaves get filled with data, it becomes critical that the use of the spectrum is maximized. This means noise immunity from other sources, as well as adjacent bands, must assure sharp band slope edges. With 40 bands to filter expected soon, Bulk Acoustic Wave technology is the answer.

Bluetooth Mesh Networks and Home Automation

En octubre 5, 2018 en All, Wireless por Traci Browne

Bluetooth Mesh, launched in 2017, addresses many of the shortcomings in existing home automation protocols already on the market. Find out how Bluetooth Mesh is poised to advance the home automation market.

Emerging Applications Put Microwave Technology to the Test

En octubre 3, 2018 en All, RF por Barry Manz

Emerging applications, such as IoT, 5G, and autonomous vehicles, pose immense communications challenges. Engineers will be put to the test to solve the current microwave technology gaps and in turn support these emerging applications in meeting their fantastic potential.

Your Mileage (and Other Things) May Vary

En octubre 28, 2016 en RF por Barry Manz

The practice of taking liberties with performance specifications to show a product in its best light is obviously nothing new in the electronics industry, and many others as well. If you’re old enough to remember, the output of stereo amplifiers and receivers was rated as “peak power”, which is typically five or six times higher than RMS power, but for the anointed it certainly makes the amplifier appear to be a real powerhouse. The output power of RF power transistors is even today sometimes specified at a single frequency where it’s highest, even though it falls off below and above it. And so on.

Terrorists Take to the Skies

En agosto 31, 2016 en RF por Barry Manz

Like most people, I suspect, when quadcopters first appeared my first thoughts were about how totally cool they are followed by, “Gee, what could I do with one?” So it’s not surprising that terrorists have asked the same question and have come up with an obvious answer: Make flying Radio-Controlled Improvised Explosive Devices (RC-IEDs), which the U.S. Central Command believes they are already working on and have possibly developed.

5G: Tall Order or Tall Tale?

En mayo 20, 2016 en RF por Barry Manz

If you believe what the wireless industry is saying about 5G, the fifth generation of cellular technology, you’d think it was the equivalent of landing a man on the moon. Not only will we have lightning-quick data rates and expanded coverage, 5G will make it possible to connect everyone with every “thing” that needs to be connected. That’s a tall order that could wind up being a tall tale, for several reasons.

5G: Not Your Average Upgrade

En mayo 6, 2016 en RF por Barry Manz

The evolution of wireless (that is, cellular) capability has promised more than its predecessor. At a high level, 2G transitioned from analog to digital modulation and added modest data to voice capability, 3G added a faster but still iffy data rates, and 4G (LTE) represented a massive improvement in speed with data rates adequate for streaming video without hiccups.

Why the Auto Industry Will Drive the Fortunes of the Microwave Industry

En abril 18, 2016 en RF por Barry Manz

The RF and microwave industry faces the same uncertainties and volatility as its more visible counterparts, but when the future has looked uncertain, a new market has serendipitously appeared to save the day. This time, although the industry overall is robust, a huge new market is beginning to emerge in the form of vehicle autonomy that will be much broader in scope than what IoT will bring. Driverless vehicle ubiquity is at least a decade or more away, but in the meantime RF and microwave hardware will be needed in steadily increasing amounts.

The Truth Is Still Out There. And We’re Still Looking.

En noviembre 12, 2015 en RF por Barry Manz

Contact is one of my favorite films, based on Carl Sagan’s book of that name, in which a great cast searches for and (thanks to scientist Jodie Foster) finds proof of alien life. There’s lots of cool RF stuff in that movie, and in many respects it pretty accurately depicts technology in action. You may have to forgive the formulaic “true believer bests the bureaucracy” element of the film. Of course, neither before nor since the film’s 1997 release has the Search for Extraterrestrial Intelligence (SETI) found anything approaching “proof” of alien life.
