GNSS antennas feature near-band filtering
Tallysman Wireless is announcing that it has added eXtended Filtering (XF) to the housed and embedded lightweight HC977XF (triple-band + L-Band), HC882XF (dual band + L-Band), and HC872XF (dual-band (GPS and GLONASS) + L-Band) precision helical GNSS antennas. Tallysman has designed the XF feature to mitigate interference from all near-band signals and ensure that the […]
MOSFETS feature low on resistance for high power density
STMicroelectronics’ STPOWER MDmesh M9 and DM9 N-channel super-junction multi-drain silicon power MOSFETs are ideal for switched-mode power supplies (SMPS) in applications from data-center servers and 5G infrastructure to flat-panel televisions. The first devices to be launched are the 650V STP65N045M9 and the 600V STP60N043DM9. Both have very low on-resistance (RDS(on)) per unit area, which maximizes power density and permits compact system dimensions. Each has the […]
Relays designed for higher reliability in isolated high-voltage environments
Building on more than two decades of experience developing new isolation manufacturing technologies and integrated circuits (ICs) for high-voltage systems, Texas Instruments introduced new portfolio of solid-state relays, including automotive-qualified isolated drivers and switches, that deliver industry-leading reliability to help make electric vehicles (EVs) safer. The new isolated solid-state relays also provide the smallest solution […]
What is “orthogonal”? (Part 2): signal space
The phrase and concept “orthogonal” is widely used in engineering, but it is also often misunderstood. The formal definition of orthogonal signals does not necessarily mean that they are unrelated or uncorrelated, although that is how the term is often used in casual “engineering speak.” Formally, two vectors are orthogonal if their dot product is […]
What is “orthogonal”? (Part 1): mechanical design
The phrase and concept “orthogonal” is widely used in engineering, but it is also often misunderstood. I was chatting the other day with a non-technical friend and said something like, “Oh, that won’t happen. Those two things are orthogonal.” My friend looked at me and replied with a “huh?” and he was right to do […]
Omni outdoor antennas cover 5G low bands
Fairview Microwave Inc. has just released a new series of 5G outdoor-rated omnidirectional antennas that cover 4G, 5G, LTE, and CBRS bands. These small form factor omni antennas are the perfect solution when broad coverage is required but traditional base station antennas are too bulky or expensive. They support 6, 7, 8, and 10 dBi…
Small dual-band antenna for IoT optimized for 868 MHz and 915 MHz
Antenova Ltd launches a new low-profile antenna displaying strong performance on both Europe’s 868 MHz bands and the US 915 MHz bands. The new antenna is named ‘Lama’, part number SRFI065. It was developed for small connected devices operating on the LP-WAN networks including LoRa, Sigfox, Wi-SUN, and MIoTy. This antenna uses the ISM frequencies […]
Advanced global-shutter image sensor for affordable, reliable driver-monitoring safety systems
STMicroelectronics is enhancing vehicle safety with its latest global-shutter image sensors for driver monitoring systems (DMSs). DMSs continually watch the driver’s head movements to recognize signs of drowsiness and distraction, enabling systems in the vehicle to generate warnings that can preserve the safety of occupants. Traffic agencies estimate that about 95% of road traffic accidents […]
Super junction 600-V MOSFETs boast fast reverse recovery time
ROHM Semiconductor announced that they have added seven new devices, the R60xxVNx series, to the PrestoMOS lineup of 600V Super Junction MOSFETs which stand out for their class-leading low ON resistance and the industry’s fastest reverse recovery time (trr). The R60xxVNx series is optimized for power circuits in industrial equipment requiring high power, such as servers, […]
