The Book End The Essential Guide to RF and Wireless Carl J. Weisman Prentice Hall PTR 232 pages; $34.99 ISBN: 0-13-025962-4 Here is a book on RF and wireless components and systems that is strictly intended for a nontechnical audience. It has two simple objectives: to provide a conceptual...

Ultra-high Linearity GaAs Mixers Infineon Technologies AG Munich, Germany Mixers are common devices in modern communication and signal processing systems. They can serve as up- and downconverters and are combined in modulators for different balanced or unbalanced configurations. Current consumption, IP3 performance and conversion loss are critical factors in...

Ultra-high Stability Miniature OCXOs MTI-Milliren Technologies Inc. Newburyport, MA The current drive for miniaturization and low cost commercialization is also affecting oven-controlled crystal oscillator (OCXO) products. Although burdened by a discrete oven that stabilizes the crystal oscillator’s thermal environment, modern OCXO designs must be smaller and less expensive than...

Electronically Tunable RF Filters for LMDS Frequencies Paratek Microwave Inc. Columbia, MD Local multipoint distribution service (LMDS) is a two-way digital wireless communication medium enabling voice, data and video traffic. LMDS applications are located in the 22 to 40 GHz range of the spectrum and provide an attractive solution...

Plastic-packaged FETs for High Power Applications Amcom Communications Inc. Clarksburg, MD With the advent of wireless communications, demands have increased for high power, high linearity and inexpensive power amplifiers. Devices capable of handling high power along with high linearity are being used to design power amplifiers that achieve the...

A Multilayer Press for Rapid PCB Prototype Fabrication LPKF Laser & Electronics, USA Wilsonville, OR Until now fabricating prototype multilayer PCBs has been a costly and time-consuming endeavor. Although single-layer prototype boards traditionally are constructed in house, designers have been forced to go to outside shops for their prototype...

A Multilevel Design Environment for Wireless System Development Applied Wave Research Inc. (AWR) El Segundo, CA Simulation techniques have been in use for many years to support the design and evaluation of RF and microwave systems. During the past three decades, computer-aided engineering (CAE) techniques have matured and are...

Shaped Sector Antennas for LMDS and MMDS Hubs REMEC Magnum Inc. San Jose, CA A line of hub sector antennas for the 24 to 42 GHz local multipoint distribution system (LMDS) and 2.1 to 2.7 GHz multichannel multipoint distribution system (MMDS) wireless access frequency bands has been recently introduced....

TECHNICAL FEATURE BENEFITS OF AUTOMATED RIBBON BONDING FOR MICROWAVE APPLICATIONS BRADLEY K. BENTON Palomar Technologies Inc. Vista, CA With today's ever-increasing need for larger bandwidth in telecommunications, datacom, aerospace and defense applications, packaging challenges continue to grow. As the frequency at which the packages are required to operate increases,...

TECHNICAL FEATURE AN ANALYSIS OF ENCLOSED COPLANAR STRIPS Abstract: With the increasing use of high speed digital circuits in modern electronic devices, coplanar stripline (CPS) transmission lines are of major importance as interconnecting lines. For example, the high speed digital circuits used in differential receivers operate best when fed...
