BAW filters keep RF interference out
Qualcomm’s ultraBAW filters cover 2.7 GHz to 7.2 GHz, keeping cellular and Wi-Fi in place. Qualcomm explains how the filters work. Each time a government auctions off a slice of spectrum for cellular use, the airwaves get more crowded as users begin occupying the new frequencies. In the days when spectrum wasn’t so scarce, cellular…
Don’t rush to choose rechargeable batteries…at least, not yet
Using energy harvesting and a rechargeable battery to power a remote wireless IoT node seems like an obvious and straightforward solution, but there are some unique aspects to consider. Don’t get me wrong: I really like rechargeable batteries; in fact, I like them a lot. Whether based on lead-acid, nickel-cadmium, lithium-ion, or other chemistry, our […]
LoRaWAN IoT networks help tame temperature-sensitive applications
The need to chill vaccines reliably during their trip cross country has highlighted the value of LoRaWAN-enabled sensors and networking. Chris Boorman, Laird Connectivity Ordinarily, cold supply chain wouldn’t be a dinner table conversation. COVID-19 vaccines, of course, have changed the situation. Specialized refrigerated containers, refrigerated vehicles, and ultra-cold storage warehouses are the foundation for […]
Power inductors feature semi-shielded wirewound construction
Bourns, Inc. released its Model SRN2012T semi-shielded power inductor series. The new inductors employ wire-wound construction on a ferrite core to offer high inductance and Q values. They also offer a superior self-resonant frequency plus low DC resistance in a compact size with an operating temperature range of -40 to +125 °C. Such features make this series […]
Signal generators feature high signal purity and frequency stability
The Rubidium signal generator family delivers outstanding signal purity and frequency stability, even at high output power levels, across a broad frequency range of 9 kHz to 43.5 GHz. Coupled with built-in, easy-to-use, at-location frequency and power calibration capability, Rubidium offers exceptional overall utility and long-term value in a broad range of commercial and military/aerospace […]
5G modules bring home the video
Aviwest designs 5G wireless modules into its video communications products, bringing video wirelessly from cameras to production rooms. Whether it’s news or sports, broadcasting from live events takes a lot of technology — and bandwidth — starting with getting a camera feed to a control room. 5G and private networks are changing the way video…
Battery charger IC handles low-voltage charging of wearables, compact IoT devices
The BD71631QWZ battery charger IC from Rohm Semiconductor is designed to provide low-voltage charging of wearables (e.g., wireless ear buds) and thin, compact IoT devices (e.g., smart displays) powered by rechargeable batteries. In recent years, the need for safer, higher density rechargeable batteries has led to the development of new battery types. This includes all-solid […]
27-GHz bandwidth socket handles Intel Atom processor E6xx series
A new high-performance BGA socket handles 0.8-mm interstitial pitch BGA 676 ball devices. The SG-BGA-6513 socket is designed for a Intel’s Atom processor and operates at bandwidths up to 27 GHz with less than 1 dB of insertion loss. The sockets are designed to dissipate up to several watts without extra heat sinking and can […]
Portable spectrum analyzers reach 26.5 GHz
New base models for the portable R&S FPL1000 take spectrum and signal analysis capabilities up to 26.5 GHz. They combine the functionality of benchtop instruments and the portability of a handheld instrument, with intuitive features to make high performance measuring on the go fast and simple. For the series, two new models have been added […]
