The value of the IoT for Electric Motors

Cees Links, GM of Qorvo Wireless Connectivity Business Unit

Qorvo

The Internet of Things, with the great amount of data it generates, produces real value, perhaps in ways you would not consider. We always think of smart homes, but industrial environments, and especially electric motors, can be a good example of the true value of the IoT.Electric motors, an essential tool of industrial lifeElectric motors come in all sizes and we all have a lot of electric motors...read more

Industrial heating applications look to solid-state devices to improve reliability and effectiveness, and save space

RF Energy

Victor Torres

Ampleon

When it comes to delivering high-power high-frequency RF energy for industrial applications, valves or ‘tube’ devices such as travelling wave tubes (TWTs), klystrons and magnetrons have been the dominant technology for well over 30 years. Over that time there has been little innovation or improvement in the technology and, suffice to say, like most mature technologies, the price is now low. While ...read more

“Horn, OK Please” to “Talk, OK Please”: The Road to Self-Driving Cars

Automotive

The ubiquitous “Horn OK Please’ sign has adorned the Indian highways for many decades now. For ages, Indian cars and drivers have used honking as a safe and secure way to let each other know many things, such as “I am passing”, “there is a havildar up the road”, “to get out of my way”. I sometimes wonder whether it was this rudimentary idea of communication that has led to the recent revolution in...read more

What are the advantages of GaN on Silicon for MMICs?

GaN

The economies of scale made possible by GaN’s propagation into commercial 4G LTE wireless infrastructure can also enable GaN’s migration into the MMICs market, where it can help system designers achieve higher levels of functionality and device integration for next-generation 5G systems.The sheer density of massive MIMO antenna configurations – scaling as high as 256+ transmit and receive elements...read more

How reliable is GaN on Silicon compared to competing technologies?

GaN

GaN-on-Si-based RF power transistors targeted for 4G LTE and 5G basestation infrastructure must adhere to, uphold and outperform the rigorous reliability testing standards achieved with legacy semiconductor technologies. GaN-on-Si RF power transistor technology has clearly demonstrated this capability, and has shown a clear pathway to support more demanding reliability requirements in the future.S...read more

Peter McNeil - L-com Global Connectivity

May 8, 2018

Dynamic range is a key parameter for many types of test and measurement equipment, analog-to-digital converters (A/Ds), digital-to-analog converters (D/As), radar receivers, and receivers in general. In some applications, a greater effective dynamic range than what the receiver hardware is capable of is required. Hence, devices, such as detector log video amplifiers (DLVA), which performs a logari...read more

Mar 12, 2018

On 21st December 2017, in Lisbon, the 3GPP TSG RAN Plenary Meeting successfully approved first implementable 5G NR specification. The completion of the first 5G NR standard enables the full-scale development of 5G NR for large-scale trials and commercial deployments as early as in 2019. This first specification was completed as part of 3GPP Release 15.As per 3GPP release 15, the frequency bands fo...read more

What is Absolute Pulling Range?

Crystal Oscillators

Raghav Kapur - everything RF

Feb 8, 2018

A VCXO is a Crystal Oscillator that varies output frequency based on an applied control voltage. The maximum variation in VCXO's output frequency over changes in control voltage under a constant supply voltage and temperature - specified in ppm - is called Pullability or Total Pulling Range.The Absolute Pulling Range is the minimum guaranteed deviation of the VCXO from the center frequency, when t...read more
