The challenge, then, becomes one of building filter-based front ends with high enough quality-factor values to provide high reflection and hence little loading when in parallel. Fortunately, a filter technology used in CDMA architectures can solve this problem, and can be produced at low cost in high volumes.

Der Chip mit Empfänger und Signalverarbeitung kommt im VQFN48-Gehäuse mit Abmessungen von 7 mal 7 mm. Erste Muster sollen bis zum Frühjahr 2005 verfügbar sein.

SAN JOSE, Calif. &#151 Apple Computer Inc. on Wednesday (Oct. 13) reported stellar results despite availability problems with its 64-bit G5 processors, according to a report from the MacCentral Web site.

Used in Apple's Mac-based computers, the 64-bit G5 processors are built on a foundry basis by IBM Corp.'s Microelectronics Group, according to analysts.

The availability of the G5 chip remains an issue at Apple (Cupertino, Calif.) In July, Apple put the blame for the delay of its iMac line squarely on IBM, the manufacturer of the 64-bit G5 processor that will power Apple's next generation consumer computers. Behind the delay, Apple executives said, was the 90-nm technology of the processors, and a lower-than-anticipated yield on such chips (see July 15 story).

According to MacCentral, Apple CFO Peter Oppenheimer said 836,000 Mac units were shipped during the quarter. Mac-based revenue was up 9 percent year-over-year, but G5 processor availability was a problem” &#151 an issue that impacted both Power Mac G5 and iMac G5 units, according to the site.

Meanwhile, for the quarter, Apple posted a net profit of $106 million, or $.26 per diluted share. These results compare to a net profit of $44 million, or $.12 per diluted share, in the year-ago quarter. Revenue for the quarter was $2.35 billion, up 37 percent from the year-ago quarter.

Apple shipped 836,000 Macintosh units and 2,016,000 iPods during the quarter, representing a 6 percent increase in CPU units and a 500 percent increase in iPods over the year-ago quarter.

We are thrilled to report our highest fourth quarter revenue in nine years,” said Steve Jobs, Apple's CEO, in a statement.

We're pleased to report 37 percent revenue growth for the quarter and operating margin above 5 percent,” said Oppenheimer in a statement. Looking ahead to the first quarter of fiscal 2005, we expect revenue of between $2.8 and $2.9 billion, operating margin above 7 percent and earnings per diluted share of $.39 to $.42.”

Design chain and supply chain teams at most companies typically work in separate divisions, fenced off from each other by bureaucratic structures and unable to offer valuable insights into common problems.

That was the situation at Lucent Technologies Inc. until a few years ago. Then, on the recommendation of partners like Xilinx Inc., the telecom equipment vendor moved its product design staff into the supply chain group. The engineering teams divided themselves into centralized functions like enclosures, which could be used by every product team. And they set up separate teams for the product-specific work.

This was happening as demand was falling apart. David Ayers, vice president of product design chain solutions at Lucent, said that it was a good time to organize engineering more efficiently. It helped, for instance, that Lucent was making fewer acquisitions that required realignment between the companies involved.
