Radmanesh Prentice Hall PTR 849 pages plus CD-ROM; $84 ISBN: 0-13-027958-7 This book is intended to be used in a two-semester course in microwave electronics for senior-level or graduate students and should serve as an excellent reference guide for...

Product Feature Cost-effective Wireless Antenna Measurement Systems MI Technologies Duluth, GA Two new antenna measurement systems have recently been introduced that add to the MI-3600 antenna measurement product line. The MI-3600 family is comprised of 20 antenna measurement systems for single- or dual-axis antenna pattern measurements in the popular...

Product Feature A Mobile Ultra-low Phase Noise Sapphire Oscillator Poseidon Scientific Instruments Pty Ltd. Fremantle, Western Australia Radar, communications, and test and measurement designers require ever-improving phase noise performance in their master oscillator. For mobile system success, ultra-low phase noise performance must be coupled with exceptional immunity to vibration...

Cover Feature 2.5 V GaAs pHEMT Switches for GSM Handsets M/A-COM Lowell, MA A new line of robust GaAs pHEMT switches for operation in 2.5 V GSM handsets has been developed. These switches feature performance that is unrivaled in the industry for harmonics at 2.5 V in addition to...

Product Feature A CMOS-based Front-end Downconverter for GPS Applications Valence Semiconductor Irvine, CA The industry is striving for single-chip Global Positioning System (GPS) designs given the limited real estate available within cell phones, personal digital assistants (PDA) and other consumer electronic devices. Since GPS designs are typically comprised of...

Product Feature Advanced Microwave Chip Capacitor Models Modelithics Inc. Temple Terrace, FL Fig. 1 Measured S 11 of a 4.7 pF 0402 chip capacitor on different thickness FR4 substrates (series configuration). The use of computer-aided engineering (CAE) software by microwave printed circuit board (PCB) designers has become commonplace. These...

Technical Feature Antenna Selection to Minimize Pointing Requirements Traditionally, when designing a satellite communications system, an allowance is made in the link budget for pointing loss. The earth station's antenna size is then selected to achieve the desired gain margin. In this article, a different approach called antenna optimization...

Technical Feature Axial Ratio Measurements of Single Circularly Polarized Antennas Robert Gunnels Andrew Corp. Orland Park, IL The measurement of antenna axial ratios must be done properly if accurate results are to be obtained. When measuring on a terrestrial antenna test range, a straightforward approach is often used whereby...

Technical Feature SOI CMOS Technology For RF System-on-chip Applications CMOS technology is one of the most promising choices for RF applications. Its highly integrated nature provides true RF system-on-chip integration. Silicon-on- insulator (SOI) CMOS offers specific additional design advantages that include a significant reduction in cross-talk between RF and...

Technical Feature Performing Transient Analysis on PLL Frequency Synthesizers A PLL can be considered a subsystem within a larger communications system, so it is appropriate to analyze this type of network with the help of a system-level simulator. The use of flexible behavioral models within the simulator allows only...
