Nujira and RF Micro Devices announced that they will be demonstrating an efficient broadband power amplifier (PA) design for 4G base stations at Mobile World Congress, Barcelona, February 2010. The design integrates the new RFMD RFG1M family of high performance gallium nitride (GaN) amplifiers with Nujira's Coolteq.h envelope tracking power modulators.

RF Micro Devices, Inc. (Nasdaq:RFMD), a global leader in the design and manufacture of high-performance radio frequency components and compound semiconductor technologies, today announced that RFMD® has production released the RF3932, a 75-watt, highly efficient gallium nitride (GaN) RF unmatched power transistor (UPT) that delivers superior performance versus competing GaAs and silicon power technologies.

Imec and its partners in the GaN industrial affiliation program (IIAP) have produced device-quality wafers with GaN/AlGaN layers on 200mm silicon wafers. With these wafers, functional GaN MISHEMTs were processed using standard CMOS tools.

GLOBALFOUNDRIES, one of the world’s leading semiconductor foundries, has signed a strategic long-term partnership on sub-22nm CMOS scaling and GaN-on-Si technology with the nanoelectronics R&D center imec.

At this weeks International Electron Devices Conference, the nanoelectronics research center imec presents an innovative, simple and robust GaN-on-Si double heterostructure FET (field effect transistor) architecture for GaN-on-Si power switching devices. The architecture meets the normally-off requirements of power switching circuits and is characterized by low leakage and high breakdown voltage, both essential parameters to reduce the power los...

As far back as 1998, Smithstown Light Engineering in Shannon, Co Clare, was in the vanguard of high-speed metalcutting, having installed the 12th machining centre ever built by the German firm, Roeders. The 3-axis, vertical-spindle machine has been in continual operation ever since and its 44,000 rpm spindle is still the fastest in the Irish manufacturer's factory.

Two Hurco VMX30t vertical machining centres (VMCs) have been added to the subcontract machine shop of Schivo Group in Waterford, on the south coast of Ireland. Compared with a VMX42 installed in 2004, the latest machines are 50 per cent more productive, due entirely to the increased functionality of Hurco's conversational programming software, WinMax, incorporated into the control systems.

The new DMU 80 eVo vertical machining centre from DMG has an overhead gantry supporting the spindle head, resulting in exceptional accessibility to the working area, including from the side, even when an automated workpiece handling system is used. The design also provides a large 800 x 650 x 550 mm working volume in a compact footprint.

German machine tool manufacturer, Hermle, has added a new model, the C 60 U, to the upper end of its range of vertical-spindle, 5-axis machining centres. Availability in the UK is through sole agent, Geo Kingsbury Machine Tools, Gosport.

The very best in 3- to 5-axis machining centres, advanced mill-turning lathes and industrial cleaning machines will be promoted on the Geo Kingsbury Machine Tools stand at Aero Engineering 2011.
