Gaps In 5G Test


Add one more industry to the long list that analysts expect 5G technology to disrupt—test. While the initial versions of this wireless technology will be little more than a faster version of 4G, concern is growing about exactly how to test the second phase of this technology, which will be based upon millimeter wave. A number of fundamental problems need to be addressed. Among them: T... » read more

Blog Review: Mar. 13


Mentor's Tom Fitzpatrick questions whether deep learning approaches can really help improve coverage in modern, complex designs. Cadence's Paul McLellan listens in at MWC as Huawei chairman Guo Ping defends the company's security practices and shows where its heading in 5G. Synopsys' Eric Huang checks out the newly announced USB4 specification, changes to previous USB names, and a few things ... » read more

MIMO And Phased-Array Antennas For 5G


Evolving communication systems are driving developments in the RF/microwave industry. The large umbrella of 5G focuses on supporting three main technologies: enhanced mobile broadband, which is the natural development of long-term evolution (LTE), massive machine-type communications, also known as the industrial internet of things (IIoT), and ultra-reliable, low-latency communications providing... » read more

Domain Expertise Becoming Essential For Analytics


Sensors are being added into everything, from end devices to the equipment used to make those sensors, but the data being generated has limited or no value unless it's accompanied by domain expertise. There are two main problems. One is how and where to process the vast amount of data being generated. Chip and system architectures are being revamped to pre-process more of that data closer to... » read more

Shedding Pounds In Automotive Electronics


Weight is emerging as a key concern for carmakers as more electronic circuitry is added into vehicles that are either fully or partially powered by batteries. As a result, chipmakers and OEMs are exploring alternative substrate materials, different types of sensor fusion, and new ways to reduce the number of wires. Adding pounds reduces driving range for electric or hybrid vehicles. The auto... » read more

The Basics of Amplitude Modulation


Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, it is far more efficient to send data by modulating it onto a higher frequency "carrier wave." Higher frequency waves require smaller antennas, use the available bandwidth more efficiently, and are ... » read more

Week In Review: Design, Low Power


Tools & IP Engineering simulation company ANSYS says thanks to new features in its ANSYS Twin Builder, product developers may be able save money in warranty and operational costs. The Twin Builder creates a digital twin of a systems in the field, enabling a convenient way to monitor and maintain systems remotely. The latest release adds predictive maintenance features for digital-twin runt... » read more

Antenna Array Design for ADAS


By Milton Lien and David Vye By implementing radar technology over the 76 to 81 GHz spectrum, advanced driver-assist systems (ADAS) enable smart vehicles with the ability to alert and assist drivers in a variety of functions, from low tire-pressure warning to collision avoidance to self-parking. These automotive radar applications use the millimeter-wave (mmWave) spectrum to exploit more ban... » read more

Design of Phased-Array Antennas for MIMO & Beam-Steering Applications


This white paper explores basic phased-array theory and the design considerations behind next-generation antenna systems. It examines the new capabilities recently added to the NI AWR Design Environment platform for developing the RF front-end hardware supporting these new antenna systems, which must be optimized for performance, reliability, compactness, and cost.

Reliability Becomes The Top Concern In Automotive


Reliability is emerging as the top priority across the hottest growth markets for semiconductors, including automotive, industrial and cloud-based computing. But instead of replacing chips every two to four years, some of those devices are expected to survive for up to 20 years, even with higher usage in sometimes extreme environmental conditions. This shift in priorities has broad ramificat... » read more
