[Cover Story]
Integrated DDS Chip Takes Steps To 2.7 GHz
Direct-digital synthesis (DDS) has long promised precise, agile control of output waveforms, although limited in frequency and often in spurious performance. The AD9956 AgileRFTM DDS from Analog Devices, Inc. (Norwood, MA), however,...  — Jon Baird , et al.

San Diego Show Draws Wireless Designers
Wireless markets may have slowed over the last several years, but wireless technology continues to advance. Many of the exhibitors at the recent Wireless Systems Design Conference & Expo pointed to aggressive product development programs as...  — Jack Browne

[Design Features]
Understanding Terrestrial Multipath Fading Phenomena
Signal-fading phenomena can drastically affect the performance of a terrestrial communications system. Often caused by multipath conditions, fading can degrade the bit-error-rate (BER) performance of a digital communications system, resulting in lost...  — Bruno Pattan

Design Finite Impulse Response Digital Filters
Wisely employing digital capabilities can result in optimum filter designs with a minimum number of bits. As was seen last month, in some cases, even having an excess amount of processing power may not result in additional filter precision. The final...  — Ricardo A. Losada

Module Melds FBAR Filter And CDMA PA
Cellular-handset design is evolving toward higher integration and the use of more "plug-and-play" modules. In support of that trend, the AFEM-7731 front-end module (FEM) from the Wireless Semiconductor Division of Agilent Technologies (San...  — Jack Browne
