The Next Generation of 802.11 Wireless LAN

December 23, 2004 7:40 am | by As next generation wireless applications emerge, higher WLAN data throughput will be required to meet expectations of performance. James Michael Wilson | Product Releases | Comments

In response to growing market demand for higher-performance WLANs, the IEEE-SA approved the creation of 802.11 TGn in 2003. The scope of TGn's objective is to define modifications to the PHY and MAC layers that deliver a minimum of 100 Mb/s throughput at the MAC SAP (see Figure 1). This minimum throughput requirement represents an approximate four-fold increase in WLAN throughput performance compared to today's 802....

RFID Tag Design

December 23, 2004 7:39 am | by Multi-dimensional technique enables fast, direct tuning of the antenna's match to the tag IC. Cory Edelman and Murthy Upmaka, Agilent Eesof | Product Releases | Comments

The interaction of the RFID reader and tag is of great interest to the RFID system designer. The environment is likely to include many reflective and absorptive surfaces as well as other tags. In addition, the increasing use of other RF systems in offices and industry means that other strong RF emitters might be operating near the RFID system, although in other frequency bands....

Compact 3G Receiver Design

December 23, 2004 7:33 am | by Arild T. Kolsrud | Product Releases | Comments

Advancements in component miniaturization and integration are paving the way for compact high-end communications receivers that do not sacrifice performance for cost or size. RF component technology is getting better, smaller, and more efficient. This makes it possible to make communications receivers smaller than ever....


Managing RFIC Test Challenges for WLAN Services

December 23, 2004 7:33 am | by Cost-effective, high-performance, reconfigurable test systems are the mantra for next generation WLAN RF components. John Lukez | Product Releases | Comments

The rapid growth of WLAN systems has created extraordinary challenges for RFIC testing. The emergence of WLAN standards is driving key performance characteristics such as channel bandwidths and data rates to unprecedented levels. To meet evolving requirements in WLAN and communications services, IC manufacturers need cost-effective, high-performance ATE systems that are easily upgradeable, maintain high-accuracy, and boost test throughput....

A Novel RFDAC Design

December 23, 2004 7:33 am | by Michael Hopkins | Product Releases | Comments

The RFDAC breaks the Nyquist frequency barrier with improved SFDR, IMD, and noise performance. In conventional RF synthesizer and modulator systems, DACs are used as baseband sources to convert digitally processed signals to analog signals, which are then filtered and applied to the inputs of analog mixers for RF upconversion....

All I Want for Christmas (or Hanukkah)...

November 23, 2004 11:17 am | Product Releases | Comments

Well, here we are at the end of another, more or less lackluster year for the telecom industry. So much for the prognosticators who swore we'd be back in rare form by Q3, '04. At the risk of getting yelled at by my readers who don't think I should step outside of the bounds of wireless, I'm going to take a bit of editorial license and maybe a bit of tongue-in-cheek-edness as well....
