LoRa eval kit aimed at metro area networks

Microchip RN2483 RN2903

Microchip has released LoRa wireless evaluation kits, claiming them to be the first on the market. They provide all the components needed to create a low-power 10 mile range network for North America (915MHz, kit DV164140-2) or for Europe (868MHz DV164140-1). Each kit includes two wireless sensors (‘motes’) based on Microchip’s RN2483 or RN2903 LoRa modules, a gateway and a ...

TI claims industry’s fastest 14bit ADC

TI

Texas instruments is claiming the fastest 14bit ADC yet with one that works at 3Gsample/s, delivering “an instantaneous 1.5GHz-per-channel bandwidth, enabling engineers to implement wideband in-phase and quadrature-component receivers beyond 2.5 GHz”, said the firm. The dual-channel ADC32RF45 can be used for direct RF signal conversion up to 4GHz,” said TI. “The first in a new data converter family, it eliminates up ...

Antenova goes for flexible antennas

Antenova, the Hatfield antenna manufacturer, is announcing three brand new flexible printed circuit antennas to cover the 3G, 4G and LTE bands. They are the company’s first flexible antennas for 4G and LTE. Together, this set of three antennas offers options for all of the world’s 4G and LTE bands, as well as a choice of antenna shape and size. ...

RFEL channeliser IP inputs bandwidth stretches to GHz

RFEL wideband CCF block diag

RFEL has added wideband input capability to its ChannelCore Flex channeliser intellectual property for FPGAs. The core was limited to input bandwidths around 300MHz. “You can now monitor multi-GHz bandwidths,” said RFEL CEO Dr Alex Kuhrt. “This enables either hardware costs to be reduced or more bandwidth monitoring to be performed for a similar system cost.” The need for wider inputs ...

Multi-band UMTS modem has global radio regulatory approval

u-blox

Alpha Micro Components is offering a small cellular module supporting 2G and 3G, which has global radio regulatory approval. The SARA-U201 from U-blox is pin and form factor compatible with its other region-specific 2G and 3G variants, such as the 2G SARA-G350, also available through Alpha Micro. Measuring 16 x 26 x 3mm, the 96-pin SARA-U201 provides 5-band UMTS, quad-band GSM. ...

Ampleon claims RF transistor lifts efficiency to next level

Untitled

Ampleon, the Netherlands-based power semiconductor firm, has introduced an RF power transistor designed for DVB-T UHF asymmetrical wideband Doherty amplifier applications. The company claims the RF device which is fabricated in a high voltage LDMOS process has greater than 50% power efficiency and the average DVB-T power output is 150W from a single transistor for broadcast applications. The Ampleon BLF888E provides ...

DLI introduces directional couplers for C X and Ku bands

DLI Knowles directional coupler

DLI, part of Knowles, has introduced 10dB and 20dB directional couplers for C, X and Ku bands. Made using thin-film high-permittivity temperature-stable materials , they are intended for commercial, military and space microwave applications. “The four port couplers are excellent for high frequency signal monitoring applications where board space is a premium and quality power detection or injection is required,” ...

Wireless M-Bus evaluation kit targets IoT

Amiho AM060

Rohm has teamed up with Amiho Technology of Cambridge to develop an sub-GHz radio for wireless M-Bus. Called AE060, it has two nodes based around Amiho’s 18 x 20mm AM060 868MHz Wireless M-Bus radio modem module, which have at their heart Rohm’s Lapis ML7345 radio transceiver. Amiho’s Wireless M-Bus stack and drivers are pre-loaded. “In addition, with security a major ...

5G at microwave frequencies will need a high bandwidth mixer, says Linear

GetFileAttachment

Bandwidth is rapidly expanding in the next generation wireless access to cope with the ever-increasing Internet traffic. The available spectrum simply cannot support the needed bandwidth. Higher frequency spectrum is being evaluated for suitability. New mixers with improved performance will be needed, write Bruce Hemp and James Wong. Also 5G wireless is expected to deliver 1Gbit/s. In order to achieve ...
