[Cover Story]
Flexible Chip Set Arms 802.11a/b/g WLANs
Wireless local-area networks (WLANs) are now well established in business enterprise networks, and growing in home applications. Until now, such networks have been based upon the IEEE 802.11b standard at 2.4 GHz. But increasing demands for more WLAN...  — Jim Bohac

Show Summarizes Microwave Technology
Microwave engineers usually mark their calendars for at least one key event each year: the IEEE's Microwave Theory & Techniques Symposium (MTT-S). Also known as the International Microwave Symposium (IMS), the high-frequency meeting is scheduled...  — Jack Browne , et al.

[Design Features]
Making Accurate Burst Measurements
Burst signals are now commonly used in commercial communications systems, such as Global System for Mobile Communications (GSM) cellular networks. Such signals are essentially pulsed RF waveforms characterized by long pulse widths and long periods...  — David Vondran

[Design Features]
Improve PCB Shielding For Portable Devices
Miniaturization of handsets and other wireless devices creates scores of shielding challenges as high-frequency components become more closely spaced. As printed-circuit boards (PCBs) shrink, new electromagnetic-interference (EMI) shielding...  — Thomas Clupper

Filtering Interference From Cellular Receivers
Interference in cellular receive systems can stem from a variety of causes. Generally, the interference starts at a base-station transmitter (Tx), either from the same cellular system or from a nearby Tx. The interference can result in dropped...  — Brian L. Wixon

Analyze Coax Cable Digital Pulse Distortion
Coaxial cables are often neglected during the characterization of high-speed digital components, even though such transmission lines can have a major electrical influence on a test setup. Coaxial cables are sometimes treated as lossy elements, and...  — Bruce Bullard , et al.

System Tests Radar Pulse Stability
Radar component and system testing usually evokes images of complex, expensive measurement systems occupying multiple equipment racks. In some cases, radar equipment designers have even used entire radar systems as a proving ground for their new...  — Jack Browne

[Product Technology]
Smart Clocks Set Timing Standards
Timing is everything in most telecommunications systems. Communications systems such as code-division-multiple-access (CDMA) cellular and synchronous-optical-network (SONET) systems rely on precise timing of transmitted data for proper operation. In...  — Jack Browne

Blind-Mate Connectors Bridge DC To 40 GHz
Blind-mate connectors simplify RF signal interfaces by allowing push-on links between different components or elements of a design. A series of blind-mate connectors from MCE/Weinschel (Frederick, MD) goes a step beyond conventional blind-mate...  — Jack Browne

[Editorial]
Looking For A Few Good Presenters
This time of year usually evokes images of travel to some distant town to attend the microwave industry's largest technical conference and exhibition, the Microwave Theory & Techniques Symposium (MTT-S). Sponsored by the IEEE, this long-running...  — Jack Browne
