Technology Filtered by - RF & Microwave

New Electronics strives to bring you all the latest technology news from the RF & Microwave sector. Advances in electronics are often fast-paced and innovative, so we know that as a design engineer you want to be kept up-to-date with current developments.

Below is a comprehensive list of all the latest electronics technology news from New Electronics.

Powerful telescopes bring us closer to the Big Bang

Humankind has always wondered what secrets the universe was hiding in its starry depths and striven to understand how we fit into the bigger picture. This curiosity is still strong, as demonstrated by the number of powerful telescopes that have either been built recently or are under construction.

Is industry ready for 5G?

Just less than a month ago, the Chancellor, Philip Hammond, used his budget speech to make a case for 5G, the next-generation mobile technology, and promised to invest £16million in a series of trials and to support research into the development of technology to underpin its deployment.

Farming embraces the IoT

The farm is perhaps the last place where you would look for advanced technology. But pressures on food production make agriculture a prime candidate for harnessing the potential of automation and the IoT. Real-time data collection is the key to improving yields and making the most of precious resources.

The choices involved in adding IP support to embedded systems

The tentacles of the internet are reaching further into the domain of deeply embedded systems that used, at most, to be attached to simple fieldbuses. Although the internet may stop short of ‘smart’ light bulbs that use Zigbee or Bluetooth to communicate, more organisations are looking at supporting the Internet Protocol (IP) directly in sensor nodes and smart actuators.

Measuring RF power in the field

The output power of an RF or microwave system is a key determinant of its performance. For this reason, signal power is measured at every stage – from design and prototyping to maintenance in the field.

Tracksure sensor system to transform rail networks

Monitoring the rail network is a costly and time consuming endeavour, but the University of Huddersfield’s Institute of Railway Research (IRR) has developed a new sensor system that could transform the way in which networks are maintained by turning rail vehicles into track monitors.

Technology to improve firefighter safety

Building fires are, by their very nature, inhospitable environments. The combination of heat, a potentially toxic atmosphere, poor visibility and an unstable building can have fatal consequences, so it’s no surprise to find out that technology is being brought to bear in an attempt to improve safety, particularly when it comes to communication with and location of firefighters committed to a building.

Developments in low cost VNAs to find new applications

As test equipment has evolved, there has been a drive to provide unique and identifiable differentiations in feature sets and capabilities, suggesting to customers they will have an advantage over their competitors by providing tighter specification thresholds. For most modern Vector Network Analysers (VNAs), this trend has led to their capabilities becoming complex, resulting in an increased cost of ownership for the user, not just in terms of capital equipment costs, and calibration and support costs, but also in the time required for user understanding and training, as well as for any control software control or drivers to be written.

Advances in technology to meet frequency mixing needs

Frequency mixing is one of the most critical sections of the signal chain and, in the past, many applications were limited by the performance of a mixer – frequency range, conversion loss and linearity defined whether a mixer could be used for the application or not. Designs for frequencies of more than 30GHz were difficult and packaging the devices at those frequencies was even harder.

LTE for the IoT: Not one standard but many

Analysts are falling over themselves predicting just how big the IoT is going to be – and it will be big. What is less certain is what will be connecting all these devices. Some companies, such as Sigfox and those in the LoRa Alliance, are rolling out dedicated networks in cities around the world. However, these have the drawback that a new network does need to be deployed and that in most cases the coverage is somewhat limited.

Irish company pioneers the development of 94GHz RF circuits for a range of applications

It wasn’t too long ago that GHz frequencies were regarded as exotic; few applications took advantage of that part of the spectrum as technology was not only difficult, but also expensive. That meant that military dominated the few applications there were. The Brimstone missile is believed to use 94GHz technology for targeting purposes, rather than the lasers used in previous missiles.

RF tests are the basis for V2X

Wireless technologies are being used to connect vehicles, but in order to ensure that messages are received accurately, developers need to adhere to minimum standards.

Linear Technology's Bruce Hemp and James Wong bring ease of use to microwave radio design

Bandwidth is rapidly expanding in the next generation wireless access to cope with the ever-increasing Internet traffic. At the same time, the current available spectrum in use simply cannot support the needed bandwidth. So higher frequency spectrums are being evaluated for suitability. Multiple options are considered, ranging from unlicensed 5.8GHz terrestrial stations, to fleets of low-orbit satellites that blanket the earth. The path to higher bandwidth lies with new higher frequencies to deliver on that promise. New mixers with improved performance will be needed. A new mixer, the LTC5549 from Linear Technology, is launched to support this effort.

Addressing key challenges in automotive infotainment test with the NI PXI Platform

Automobiles have experienced rapid growth in the amount of in-vehicle electronics in recent years and a key area where these electronics are playing a vital role is in the infotainment system of the vehicle. In fact, the infotainment systems have become somewhat of a hub for a number of functions of the vehicle, and represent where both large amounts of information and driver entertainment are converging. Not only do they continue to blur the line between the driver’s mobile phone and the car for entertainment purposes, but there is also an overlap with important components of advanced driver assistant systems (ADAS).

While smart textiles for wearables remains in its infancy, its potential is huge

E-textiles or smart garments, smart clothing, electronic textiles, smart textiles, or smart fabrics; whatever the definition, they all have a digital component or electronics embedded within them. While it may still be in its infancy, it is a fast growing market with new capabilities being developed that will enable users to interact with their surroundings and to communicate data via embedded sensors or conductive yarn through the clothes they wear.
