Featured Technology The Testing Needs of WLAN Technology

August 30, 2004 7:07 am | Product Releases | Comments

In order for Wireless LANs to achieve the performance demanded by corporate buyers, equipment and chipset manufacturers will need better test equipment. By Dr. Thomas Alexander, Rick Denker, and Gerard Goubert Today's WLANs resemble the early days of cell phones, whose first users were driven by the great convenience, and whose later users demanded much more sophisticated features and reliability: the transparent roaming, compact equipm...

Cover Story Integrating Ultra CMOS Designs in GSM Front Ends

August 30, 2004 7:06 am | Product Releases | Comments

Today's handsets require an RF front-end that can select between transmit and receive, as well as select different frequency bands. New processes remove the size and bulk associated with traditional switching devices. By Dylan Kelly Early handset designs could duplex between transmit and receive using a circulator (see Figure 1a)....
