Ericsson has launched three new radios in its Massive MIMO portfolio and expanded its RAN Compute portfolio with six RAN Compute products to accelerate 5G mid-band rollouts based on . Ericsson Silicon – the company’s SoC range. With new mid-band spectrum available, communications service providers can leverage their 5G spectral assets to roll out services quickly and efficiently to deliver ...

The Insight SiP ISP1907 series of Bluetooth Low Energy modules are based on Nordic Semiconductor’s nRF52 SoC and uses Bluetooth 5.1’s direction finding for object and ID tracking. The modules are available now from Rutronik UK. The modules are claimed to have a long battery life and are suitable for use in professional and private IoT applications, from offices to ...

RF Solutions has created a single-channel remote control problem-solver that can switch up to 1kW of mains load. Called RF Ferret, it has a 21 x 76mm footprint and uses change-over relay as an output. There are, or will be, three RF Ferrets: Ferret-4R1 433MHz 6-24V in the pipeline Ferret-8R1 868MHz 6-24V Ferret-9R1 918MHz 12V in the pipeline All can be switched ...

U-blox has combined LPWA (low-power wide-area) connectivity and GNSS (satellite navigation) into a single 14 x 14 x 1.5mm package – half the size of the company’s functionally-similar Sara-R5 module (16 x 26 x 2.2mm). Called Alex-R5, it is based on u-blox’ secured UBX-R5 LTE-M and NB-IoT, plus its M8 GNSS chip. “By bringing all technology building blocks in-house and ...

A new whitepaper available on Electronics Weekly details energy harvesting for remote switches using Zigbee, for example for use in Smart Homes and Buildings. Download the whitepaper » Written by On Semiconductor, with an IoT focus, it covers how best to achieve the benefits of wireless, battery-free switches. It writes: “These devices offer unparalleled flexibility for deployment within buildings because they do not require ...

ST’s BPF8089-01SC6 RF front-end for GNSS integrates the impedance-matching and ESD protection circuitry typically implemented using discrete components. The device provides a 50Ω matched interface between the receiver’s antenna and low-noise amplifier (LNA), and is ready to plug-and-play with ST’s STA8089 and STA8090 LNAs. The chip typically replaces a matching network containing up to five capacitors, resistors, and inductors, as well ...

Smiths Interconnect has released a series of high frequency surface mount chip equalisers for controlling gain variation up to 40GHz with a maximum slope of 4dB. Called the CEX series, the parts combine thin-film and thick-film processing, offer multiple slope (1-4 dB) and band options. They come in standard and high-frequency versions. In the high-frequency types (see photo) Slope linearity of ...

Martin Woolley, Senior Developer Relations Manager, EMEA, at Bluetooth SIG, considers how Bluetooth technology operates to mitigate interference and increase reliability, with adaptive frequency hopping (AFH). Wireless communication systems usually employ radio as the underlying, physical basis for getting data from one device to another. Bluetooth itself is a radio communications technology. But there’s a problem. Radio is undeniably, unambiguously, ...

Renesas has announced a 60W wireless induction power receiver IC, compliant with WPC 1.2.4 and compatible with WPC 1.3+. Called P9418, it can also deliver up to 5W as a wireless power transmitter. Power is transferred through an external LC coupling tank. As a receiver, the device has a all-n-channel synchronous full bridge rectifier to convert the incoming ac power signal ...

NXP has announced a suite of 77GHz tranceivers and radar processors “that address NCAP requirements for corner and front radar applications while offering ‘4D’ imaging radar’s first commercially viable path to volume production, according to the company. ‘4D imaging’ radar adds direction, angle of arrival and elevation measurement to simply measuring range and speed. The parts are the S32R294 processor, the S32R45 processor and TEF82xx ...
