Antenna for 2.4-GHz wireless LANs debuts
News & Analysis  
10/29/2003   Post a comment
Pacific Wireless has introduced an omnidirectional, extended-range "rubber duck" antenna for wireless LANs operating at 2.4 GHz and meeting the 802.11 standard. The Model IN24-5RD provides a 5.5-dBi gain rather than the industry-standard 2.2 dBi, thus doubling the signal strength for WLAN communications, the company said. It provides a 360 degrees horizontal transmission pattern and a 50 degrees vertical transmission pattern.

MEMS: The Applications Triage
News & Analysis  
10/21/2003   Post a comment
Emerging MEMS applications have one challenge in common with virtually all entrepreneurial technology companies: They must find a way across the chasm between the early adopters of new technology and the "early majority adopters." If they don't, they become—at best—a niche company or application. Jack Shandle reports on a panel at the recent MEMS Executive Forum.
SMT inductors boost power up to 32 amps

Fox Electronics claims to offer the smallest miniature watch crystal, measuring 3.2 mm x 1.2 mm with a low profile of 0.95 mm. This new FSN watch crystal can be used in space-constrained applications such as handheld and portable devices.
Array packaging shrinks component size, cost
News & Analysis  
10/2/2003   Post a comment
Driven by portable-appliance designers' miserly space allotments for electronics, component suppliers are integrating capacitors and resistors into arrays and networks and are increasingly turning to chip-scale and ball-grid-array packaging. The advantages, aside from the obvious space savings, are assembly cost reductions as well as faster throughput. Gina Roos has these insights.

Leveraging its expertise in ceramic-based materials and processes, Murata Electronics has developed a new line of multilayer caps, ranging up to 100 microfarads, to replace both aluminum and tantalum devices.
Focus on components in Asia
Product News  
10/1/2003   Post a comment
As manufacturing continues to migrate from the United States and Europe to China, North American components distributors are taking a hard look at what it means to support their customers and what it will take to have a major presence in China.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
