Nordic Semiconductor, the wireless comms specialist, has expanded its nRF52 series with the nRF52805 Bluetooth 5.2 SoC. Supplied in a wafer level chip scale package (WLCSP), it measures 2.48 x 2.46mm and is optimised for two-layer PCBs enabling designs that are small and low cost, says Nordic. The nRF52805 includes a 64-MHz 32-bit Arm Cortex-M4 processor with 192KB Flash and ...

The ST STEVAL-IDB008V1M Bluetooth Low Energy 5.0 (BLE) evaluation platform accelerates application development with modules featuring BlueNRG-2, the Company’s second-generation BLE System-on-Chip (SoC). BlueNRG-2 supports the Bluetooth 5.0 certification, which allows enhanced security with LE Secure Connections, power-efficient privacy with Link Layer Privacy 1.2, and up to 2.6-times higher throughput with LE Data Length Extension. The SoC contains an Arm Cortex-M0 core ...

Rutronik is offering two miniature CMOS wideband RF antenna diversity switches from Infineon, operating across 50MHz to 6GHz. Both are specifically designed for WLAN and Bluetooth and will operate at 26dBm (CW, 1.1 VSWR, 50Ω) BGS14WMA9 is a single-pole four-way in a 9pin SMD 1.1 x 1.1 x 0.55 mm package Its bandwidth also allows use with FM Radio, LTE, ...

The Bluetooth SIG has announced a partnership with DiiA, an alliance of companies from the lighting and sensor industries. The aim is to speed the adoption of IoT-enabled commercial lighting. The collaboration, it states, will enable the deployment of certified DALI-2 devices and intelligent D4i luminaires, with qualified Bluetooth mesh intelligent lighting-control networks, bringing together two IoT approaches for commercial ...

Erzia Technologies has announced a series of rf wide-band high-power amplifiers (WHPAs) that offer both broadband frequency coverage and consistent output power throughout bands as high as E-band. “These wide-band designs are among the first of their kind to be capable of withstanding the harshest environments while holding output power in place,” claimed the company, adding that it developed the ...

Siglent SSG5000X-V is a 6GHz signal generator with vector capability “which now gives the company RF generators that address the complete sub-6GHz communication frequency range. This includes the latest NR-5G Band [FR1], which is located between 3.4 and 3.7GHz”, according to Siglent. Phase noise is -120dBc (1GHz 20kHz offset) with regulated maximum output to +20dBm (settable up to +26dBm) and ...

Wireless communication in mmWave bands, which range from 20 GHz to 300 GHz, is expected to be a key enabling technology for 6G wireless systems, because the huge available bandwidth can accommodate ultra-high data-rate communications. Within that range of mmWave bands CEA-Leti’s research is investigating D-band, a new spectrum at 140 GHz that may play a major role for 6G ...

Silicon Labs has introduced a line of multi-rail power chips (PMICs) for its EFR32 and EFM32 wireless MCU families. The family covers input voltages from from 0.8V to 5.5V, although no single device covers the whole range. Part Vdd output configuration (see data sheet) EFP0109GM20 1.8 – 3.6V 1.7 – 3.3V wired boost EFP0108GM20 0.8 – 1.8V 1.7 – 3.3V single-cell ...

Exxelia’s CH series of surface-mount ceramic capacitors are designed with high Q-factor and stable operation for rf applications in medical MRI scanners, scientific, industrial and cellular base stations Options ranging across 0.1pf to 1,000pF and 50V to 1500V are available with low ESR, high-Q and high self-resonant frequencies (see graphs). They are “available with nickel or non-magnetic copper barrier and tinning. ...

STMicroelectronics has integrated common-mode filters and ESD suppression into automotive data line protectors. “These are the first common-mode filters on the market with automotive-grade qualification and automotive surge compliance guaranteed,” claimed ST. “They are not only produced and qualified according to AEC-Q101 requirements but are also designed and tested against automotive surge specifics such as ISO10605.” The products each protect ...
