Automobiles rely more and more on a growing number of wireless technologies to communicate with the outside world. Long-term technology goals include vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2X) communications for millions of automobiles as collision-avoidance and other intelligent transportation applications, which can be met using the IEEE 802.11p standard over the 5.9 GHz Dedicated Short Range Communications (DSRC) band. Avoiding interference in these applications requires high-performance RF bandpass filters capable of operating at high frequencies.
Scientists from the University of Nebraska-Lincoln (UNL) have invented a type of concrete mixture that can shield electronic systems from electromagnetic pulse (EMP) attacks and coronal mass ejections (CMEs). It's a cost-effective alternative to current EMP shielding solutions like metal enclosures.
A limiter PIN diode with a three-layer design can protect a receiver from large input signals while allowing the receiver to function normally when large signals aren’t present. A diode can also be used as an input-power-controlled RF variable resistance to produce attenuation that is a function of the diode characteristics as well as the incident signal amplitude. This application note describes the use of PIN limiter diodes in receiver protectors in detail, as well as their many design characteristics and benefits.
The rapid proliferation of insecure internet-connected devices and systems is threatening critical healthcare, financial, transportation, energy and other infrastructure, to the extent that government and industry should be working together more closely than ever to mitigate risks.
While today’s carrier networks are better than previous generations, providers have a lot of ground to cover to reach the goals promised with 5G technology. In addition to being “greener” for the environment, 5G has goals of 1 ms latency, 100 x network energy efficiency, 20 Gbps peak data rates, and 10 Mps/m2 area traffic capabilities. So, how do we achieve the RF chain 5G objectives and meet ‘green’ network goals? This article discusses how RF Gallium Nitride (GaN) technology can be used for emerging 5G technologies.

AT&T today announced its 5G Evolution plans for 2017 and beyond, and highlighted its other initiatives to expand and enhance ultra-fast internet access for millions of customers.
An antenna is a device which transmits and receives radio-frequency signals. It converts electrical waves into radio waves and vice versa. Transducers are used for conversion of electric waves into radio waves.
A team of University of Illinois researchers has recently advanced gallium nitride (GaN)-on-silicon transistor technology by optimizing the composition of the semiconductor layers that make up the device.
