In brief: Cree, Johnson Matthey, Skyworks, IXYS

Cree's power LEDs are qualified for 1 A operation; Poland's Institute of Electronic Materials Technology receives new hydrogen purifiers from Johnson Matthey; Skyworks posts a profit; and IXYS' GaAs chip making subsidiary MwT targets MRI scanners with its new amplifiers.

More power to Cree
Cree's high-power XR-E LEDs have been qualified for up to 1 A operation, a drive current at which the chips emit up to 210 lumens.

The company's XLamp products that feature the chips are now said to be qualified for extended performance in applications like flashlights. The qualification applies to XR-E LEDs already in the field, which can now be driven at the higher rating.

Polish institute gets pure hydrogen
Johnson Matthey has delivered two HP-480 VPurge hydrogen purifiers to the Institute of Electronic Materials Technology (ITME) in Warsaw, Poland.

ITME will use the systems during epitaxial growth of n-type and p-type layers of silicon carbide for high-frequency electronic devices.

The purifiers are based around palladium membranes that provide 99.9999999 percent pure hydrogen gas.

Streamlined Skyworks posts profit
GaAs chip and component manufacturer Skyworks Solutions posted sales of $196 million for the quarter that ended on December 29.

Having curtailed its baseband business and restructured to focus on analog and RF products early in the quarter, the Woburn, MA, firm also registered a net profit of $21.4 million "“ a new record for Skyworks "“ before taking into account restructuring and other one-time charges.

IXYS targets medical imaging
Microwave Technology (MwT), the GaAs manufacturing subsidiary of IXYS Corporation, is hoping to penetrate the medical imaging equipment market with a new line of high-performance pre-amplifiers.

Made at MwT's 35,000 ft2 GaAs fab in Fremont, CA, the penny-sized pre-amps are said to be ideal for use in magnetic resonance imaging (MRI) scanners.

Operating at between 43 MHz and 127 MHz, the low-noise amplifiers dissipate only half the heat of conventional pre-amps, says MwT.
