First LoRa IoT transceiver cleared by Alliance

Microchip LoRa

Microchip has won the race to get a transceiver module through the LoRa Alliance’s certification program after Espotel’s test lab cleared its RN2483 module to the LoRaWAN 1.0 specification for operation in the European 868MHz licence-free band. LoRa is one of the wireless protocols competing for IoT applications like smart metering. It has security and offers metropolitan area coverage for low ...

Sea water fountain is RF antenna

Mitsubishi SeaAerial

Mitsubishi has invented an antenna made from sea water. Branded SeaAerial, it shoots a column of water into the air to create a conductive plume for transmission and reception. “A plume of seawater can be used as an antenna if it is insulated, so Mitsubishi Electric developed an insulated nozzle that transmits radio waves to the antenna even when the ...

GPS module gets access to Galileo

uBlox NEO-M8Q

Swiss GPS module maker uBlox has added Galileo satellite navigation reception to its M8 series. Galileo reception comes as part of the FW 3.01 software update and allows any M8 product to track: Galileo, GPS, GLONASS, BeiDou, QZSS and SBAS. BeiDou acquisition sensitivity has been boosted, and the Indian GAGAN augmentation system added. Power consumption is said to be improved by 10%. Up ...

VCO+PLL cuts phase noise in basestations

ADI ADF4355

Analog Devices is aiming at basestations with a phased-locked loop (PLL) synthesiser with integrated voltage-controlled oscillator (VCO). Called ADF4355, typical phase noise is -144dBc/Hz (1MHz offset) at 1.7GHz (typical), integrated jitter is ~150fsrms and the IC operates up to 6.8GHz. “The device’s higher frequency band offers throughput advances for makers of point-to-point microwave links, point-to-multipoint microwave links, satellite systems, VSAT ...

TV remotes get voice activation with Bluetooth

tDTCVDefkXLk1AVqfg0M2twnhzHJieGgLepT29nzKf8

Nordic Semiconductor has introduced a reference design for the development of TV smart remotes which use Bluetooth, writes mobile reporter, Tom Wilson. The nRFready Smart Remote 3 reference design is implements voice input and speech recognition control, a 6-axis motion sensing ‘Air-mouse’, multi-touch trackpad technology, plus 39 developer-programmable buttons and legacy IR hardware support (to control IR-only products). Nordic Semiconductor ...

IQ modulator design needs measurement accuracy, says Linear Tech

13jan16evmfig1

How to optimise digital modulation accuracy in an IQ modulator? Bruce Hemp and Peter Stroet from Linear Technology describe how a vector signal analyser helps optimise EVM performance of the LTC5598 direct quadrature modulator. EVM, or error vector magnitude, is essentially a scalar measurement of digital modulation accuracy, an important figure of merit for any source of digital modulation. Low ...

Signal booster chip makes NFC transactions more reliable

04nov15ams

AMS says it can speed up the transaction speeds of NFC (near field communications) with an analogue front-end device which includes a signal booster. The supplier claimed the device can improve the reliability and perceived speed of NFC transactions even with applications that use a small antenna. The AS3921 with the booster technology implements active load modulation: it generates an ...

Start-up says multi-band LTE is possible in CMOS

ACCO AC26120

CMOS RF chips continue to make an impact on mobile phone design and a US-based start-up has developed a CMOS power amplifier which will support multi-band 3G/LTE designs, writes mobile reporter Tom Wilson. ACCO Semiconductor says it is in production of a CMOS Multi-mode Multi-band Power Amplifier (MMPA) which supports quad-band GSM/EDGE and 12-band 3G/LTE smartphones. “The AC26120 represents a fundamental ...

Tiny IoT radio for smart meters

AM060 ruler

A tiny radio module for connecting smart meters to a local hub or gateway has been designed by Cambridge-based Amiho Technology in partnership with Rohm subsidiary Lapis semiconductor. The AM060 radio module, which measures just 17.8 x 20.2mm, operates at the Wireless Meter-Bus standard of 868MHz. It has built in data flash specifically for smart metering and other IoT applications. For ...

Sub-1GHz ISM transceiver approved in Europe, US and Canada

LPRS eRIC9AC

LPRS’ eRIC9-FCC wireless transceiver modules are available for use in ISM (Industrial, Scientific and Medical) bands of 868MHz for the UK and Europe, and 915MHz for the USA and Canada. They have FCC certification for use in the USA and IC approval for use in Canada, as well as all European approvals “reducing the complexities OEM’s can face when submitting ...
