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

IoT-connected vehicles will challenge car firms
The growing importance of the internet for providing data services and data analytics is creating challenges for automotive suppliers, which will be very familiar to IT firms, writes Andrew Macleod In the past market needs for consumer electronics, computer networks, and the automotive industry were very separate, each with their own design cycles and security ...
48V dc-dc converter protected to 76V for industry
Rohm has announced a 12-76V input, 3A variable output voltage, dc-dc buck converter with integrated mosfet. Called BD9G341AEFJ, it is optimised for industrial use. The high max voltage is there to “ensuring sufficient margin against sudden surge voltages, such as those caused by lightning, in communication infrastructure , factory automation equipment, industrial machinery, and other applications that normally ...
EU denies net neutrality, delays abolition of roaming charges
The European Parliament has refused to endorse net neutrality while postponing until June 2017 the abolition of roaming charges. Roaming charges were to have been abolished this year but the European Council blocked it. National governments decide European Council rulings and governments like the UK’s have fought against the abolition of roaming charges. In April ...
Keysight takes PXIe signal analyser to 5G
Keysight Technologies has introduced a 50GHz frequency extension to its M9393A PXIe vector signal analyser (VSA), which means it covers Ka-band frequencies and millimeter wave (mmWave) measurements. This frequency band is used for satellite comms and mmWave has also being researched for 5G mobile. The module has options to allow for continuous frequency sweeps from 3.6 to 50GHz (option FRX) ...

Taking the brakes off cuprate superconductors
Cuprate superconductors might work at higher temperatures, if only someone could find a way to take the brakes off. The brakes in this case are an electron energy density wave – fixed electrons that inhibit free-flying electrons, according to the US Brookhaven National Laboratory. “Many researchers believe that the density wave is the key to ...
