A new series of high frequency couplers target 5G telecommunication, automotive radars, satellite communication, point-to-point radios and aerospace applications. Pasternack’s new line of high-frequency RF directional couplers consists of 24 models that have a high maximum operating frequency range from 26.5 GHz to 67 GHz. These new couplers deliver excellent isolation, low insertion loss and […]
PC-based scopes combine real-time, equivalent-time sampling
The PicoScope 9400 Series is a new class of SXRTO oscilloscopes that combine the benefits of real-time sampling, equivalent-time sampling and high analog bandwidth. The PicoScope 9404 Series SXRTO oscilloscopes have four input channels up to 16 GHz with market-leading ADC, timing and display resolutions for accurately measuring and visualizing high-speed analog and data signals. […]
A better way to measure lidar
The special demands of sensors needed for autonomous driving have brought suggestions for different measurement metrics. Leland Teschler, Executive Editor A few months ago, sensor maker AEye made a media splash when it claimed it had developed a super-speedy lidar sensor that could hit a scan rate of 100 Hz or more. That speed outpaces […]
Thermal/visible microscope handles PCB repairs
The QianLi LC-IRP01 Thermal Imaging Camera is a diagnostic tool for PCBs which displays heat images to help identify damaged or malfunctioning components or short-circuits. The QianLi LC-IRP01 Thermal Microscope contains two imagers, one for visible wavelengths and one for infrared heat images. These images can be combined on a PC display to quickly identify […]
Saelig to carry Rigol MSO8000 2-GHz 4-channel digital scopes

Three models are available with input bandwidths from 600 MHz to 2GHz, each with 4 analog channels. The series […]
What high-speed data means for connected vehicles
Technologies behind multigigabit Ethernet and 5G could transform transportation. Harsh Patel | Molex The connected vehicle segments are growing at a rapid pace. By 2020, industry analysts predict there will be 250 million connected vehicles and 10 million self-driving cars on the road, and 470 million connected/autonomous vehicles by 2025. As the number of connected […]
Advanced circuit protection for connected autonomous vehicles
New protocols for high connectivity need robust protection for reliability and safety. James Colby | Littelfuse, Inc. At the turn of the century, automobiles hosted many electronic systems that were basically independent. Since then, the growth of connectivity and rise of artificial intelligence and machine learning have changed automotive electronics dramatically. Vehicles of all types […]
Keeping connected electronics cool with thermoelectric modules
Future connected vehicles are characterized by clusters of densely packed electronics. Thermoelectric modules can keep the temperature of these hot spots at manageable levels. Andrew Dereka | Laird Thermal Systems Advances in automotive electronics tend to come in small packages where dense circuitry squeezed into a pint-sized footprint generates lots of heat and thermal challenges […]
Flash memory keeps cars connected
A new kind of flash memory is optimized specifically to handle the hostile environment imposed on electronics in vehicular uses. Leland Teschler | Executive Editor You’d have to say the NAND flash memory had an inauspicious beginning. Invented in 1987 by Toshiba, the first NAND flash chip didn’t sell until 1995 when it finally found […]
Tech refresher: Basics of flash, NAND flash, and NOR flash
Flash memory stores information in an array of memory cells made from floating-gate transistors. Each memory cell resembles a standard metal-oxide-semiconductor field-effect transistor (MOSFET) except that the transistor has two gates instead of one. The floating gate (FG) and the control gate (CG) control the current flowing between the source and drain. The CG resembles […]
