Toshiba upgrades RF SOI process


Toshiba claims that RF switch ICs, fabricated using the new TaRF8 process such as the new SP12T  process, achieve the lowest insertion loss  in the industry of 0.32dB at 2.7GHz.

Sample shipments of SP12T RF switch ICs fabricated with the new process will start in January 2016.

Designed for use in smartphones, the SP12T RF switch IC features an integrated MIPI-RFFE controller for mobile applications. The device is suitable for use in devices compliant with 3GPP GSM, UMTS, W-CDMA, LTE and LTE-Advanced standards.

Products utilising the new TaRF8 SOI-CMOS TarfSOI front-end process achieve an insertion loss of  0.32dB at 2.7GHz. Compared with products using Toshiba’s current TaRF6 process, insertion loss is improved by 0.1dB while maintaining the same level of distortion characteristics.

With the trend in mobile communications towards high data rate, high-capacity data transfers, RF switch ICs used in mobile devices and smartphones, require multi-port support and improved RF performance. Lowering insertion loss is recognised as a particularly important factor in this, as it decreases RF transmission power loss, which can support a longer battery life for mobile devices.

LuxLive: UK LED builds UK lighting factory

UK LED Lux Live

The firm is both a maker of LED lighting and a service-provider – it replaces existing lighting with LED lighting for business, industry and local government customers in the UK.

Products include a recently-developed street lamp (see photo) using Bridgelux CoBs and custom optics. The street lamp is pre-certified for power consumption – street lamps are not metered, so power companies charge per lamp at a fixed power level – allowing local authorities to install it without further paperwork. It’s other big sellers are LED replacements for fluorescent tubes.

Why build a UK factory in addition to a perfectly good Chinese factory?

“Freight costs from China and rising labour costs in China are the biggest factors,” UK LED co-owner Colin Griffiths told Electronics Weekly. “Together these equal labour costs in the UK. Then there is the time-to-delivery.”

UK LED is based in the Wirral and has facilities in The Midlands, Wales, and China.
