The Book End Fundamentals of Applied Electromagnetics Fawwaz T. Ulaby Prentice Hall 433 pages plus CD ROM; $92 ISBN: 0-13-011554-1 Electromagnetics (EM) courses in college are undergoing major changes similar to many other technical subjects. This book bridges the gap between electric circuits and EM and provides coverage of...

An Advanced Integrated Layout Editor Applied Wave Research Inc. (AWR) El Segundo, CA An advanced integrated layout editor is featured in the latest upgrade to Microwave Office™ version 3.0 CAD software. The new Apollo layout capability complements Microwave Office's existing circuit simulation and electromagnetic (EM) analysis tools by expanding...

An Interactive Internet Service That Provides On-line Circuit Design Merrimac Industries Inc. West Caldwell, NJ As the Internet changes the world's concept of entertainment, information, finance, commerce and hundreds of other disciplines, it remains relatively unexplored by the RF and microwave industry for much more than catalog perusal. However,...

Temperature Sensing Terminations Florida RF Labs Inc. Stuart, FL In normal operation, most terminations never see high power. They terminate circulators and couplers, which in normal operation transmit little or no power to the termination. Whenever power is being dissipated in a termination, it is usually a sign that...

A Fiber-optic-based Programmable Delay Line Princeton Electronic Systems Inc. (PES) Princeton, NJ An important application of optoelectronic devices in microwave signal processing is optical delay lines. Optoelectronic devices with wide bandwidth, high dynamic range and small size play a crucial role in the performance improvement of signal processing systems....

DC to 110 GHz Measurements in Coax Using the 1 mm Connector The 1 mm coaxial connector was designed to provide an enabling technology for test systems that work up to 110 GHz. It was introduced as an open standard to the RF and microwave industry through the IEEE...

Technologies for Wireless Applications: Past, Present, and Future Peter Staecker Microwave Journal Guest Editor This special section contains articles based on papers originally presented at the IEEE MTT-S International Topical Symposium on Technologies for Wireless Applications held in Vancouver, BC in February in conjunction with INTER COMM® '99. The...

Characterization of a Double-doped Power HJFET for W-CDMA Cellular Handset Application Demands on next-generation wideband CDMA (W-CDMA) handset transmitters (and thus power devices) include high linearity and high power-added efficiency (PAE) under low voltage supply. A power heterojunction FET (HJFET) has been developed for such applications, achieving a high...

Planar Integrated Antenna Technology Over the last several decades, the development of planar antenna technology has fundamentally changed the microwave and millimeter-wave communication fields. Planar antennas can be printed on dielectric substrates with minimal cost and processing. In many applications, these compact and low profile antennas offer an inexpensive...

Correlation between Ungated Recess Width and Linearity of GaAs MESFETs Intermodulation distortion and adjacent-channel power ratio (ACPR1) performance of GaAs MESFET discrete and MMIC power amplifier (PA) devices has been found to be dependent on the width of the ungated recess. Devices with wide ungated recess exhibit soft gain...
