Agilent teams up with Davis to speed terahertz technology


AGILENT TECHNOLOGIES and the University of California, Davis, are setting up the “Davis Millimetre Wave Research Centre”.


The DMRC will focus on advancing technology in millimetre wave and THz systems for radar, imaging systems, sensors, communications and integrated passive devices found in electromagnetic metamaterials and antennae.


The DMRC is vertically integrated, with research involving devices, integrated circuits, packaging, metamaterials and defected ground integrated passives, imaging systems, THz vacuum electronics, THz micro-machined devices, nonlinear modelling, nanomaterials and wireless implantable devices.


These devices and systems are found in commercial products such as medical imaging systems, security scanners, gigabit wireless communications devices and sensors, as well as defence usages such as radar and active denial systems. The first aim of the new centre is to


establish a core test facility with measurement capabilities that include Agilent nonlinear vector network and spectrum analysis test equipment up to 325 GHz. These facilities will support gigabit wireless communications at 60 GHz and 80 GHz, as well as the imaging, radar and active denial systems to 325 GHz.


“In launching the DMRC, our goal is to become a premier millimetre-wave research centre nationally and internationally,” said Linda P.B. Katehi, chancellor of UC Davis. “With this new facility, UC Davis will be able to expand the research, and recruit outstanding graduate students and faculty.”


“Agilent is delighted to support UC Davis’ research into millimetre wave technology,” said Gregg Peters, vice president of Agilent’s Component Test Division. “Millimetre wave implementation has broad industry impact, and our many first-to-market test solutions are ideal tools for revealing the information critical to their work.”


Cree’s record revenue of $988 million is thanks to LED lighting


CREE has announced revenue of $243.0 million for its fourth quarter of fiscal 2011, ended June 26, 2011. This represents an 8% decrease compared to revenue of $264.6 million reported for the fourth fiscal quarter last year and an 11% increase compared to the third quarter of fiscal 2011.


For fiscal year 2011, Cree reported revenue of $987.6 million, which represents a 14% increase compared to revenue of $867.3 million for fiscal 2010.


“Q4 results were in-line with our targets, and we are encouraged by the 11% sequential growth in quarterly revenue,” stated Chuck Swoboda, Cree chairman and CEO. “Over the last fiscal year, we


continued to have success leading the LED lighting revolution and growing our LED lighting business, while at the same time managing through a challenging business cycle for our LED component and LED chip product lines.”


For its first quarter of fiscal 2012 Cree targets revenue in a range of $245 million to $255 million with GAAP and non-GAAP gross margin targeted to be in a similar range as Q4 at 38-39%. GAAP operating expenses are to increase by $2.0 million to $75 million. The tax rate is targeted at 20% for fiscal Q1. GAAP net income is targeted at $16 million to $19 million, or $0.14 to $0.17 per diluted share. The GAAP net targets are based on an estimated 110.2 million diluted weighted average shares.


Emcore’s GaAs cells launched in final space shuttle mission


A pair of Emcore Inverted Metamorphic Module Quadruple-Junction (IMM4J) solar cells were carried on a platform from the Space Shuttle Atlantis’ cargo bay on July 20, 2011 after Atlantis undocked from the International Space Station during its historic final mission. Emcore says its IMM4J large-area solar cells, with solar-to-electric conversion efficiencies in excess of 33percent, are amongst the highest efficiency solar cells ever launched into space. The IMM4J solar cell technology, which is currently under development, has also demonstrated a laboratory world record conversion efficiency of greater than 36percent, measured under simulated space solar illumination conditions at Emcore.


“The on-orbit data from these cells provides an invaluable opportunity for Emcore to assess the performance of our latest solar cell technologies under space flight conditions,” said Christopher Larocca, Chief Operating Officer of Emcore. “We are also very proud to make a contribution to the final mission of the Space Shuttle program.”


Emcore is one of the world’s largest manufacturers of highly efficient radiation-hard solar cells for space power applications. With a beginning- of-life conversion efficiency in the order of 30 percent and the option for a patented, onboard monolithic bypass diode, Emcore’s multi-junction solar cells can provide extremely high powers to interplanetary spacecrafts and earth orbiting satellites.
