International Report NIIP Launches New Phased-array Fighter Radar Russian radar contractor Nauchno-Issledovatelskiy Institut Priborostroyeniya (NIIP - Scientific Research Institute for Instrument Engineering) used the September Farnborough International Airshow to launch the lightweight Osa (Wasp) phased-array fighter radar. At the show, the Osa radar was fitted to the displayed Mikoyan...

The Book End The RF and Microwave Circuit Design Cookbook Stephen A. Maas Artech House Inc. 267 pages; $65, £52 With the vast majority of engineers challenged to produce effective hardware designs in record time, it is refreshing to pick up a book that is aimed at these individuals...

140 GHz Extender Modules for Vector Network Analyzers Anritsu Co., Microwave Measurements Division Morgan Hill, CA For nearly the entire history of microwave communications, the characteristics of the mm-wave spectrum between 100 and 140 GHz have intrigued scientists and designers alike. The future of this formerly remote portion of...

A Three-channel Vector Modulator with Reference Channel Merrimac Industries Inc. West Caldwell, NJ A new and unique packaging technology has been introduced for commercial and military microwave components and subsystems. Multi-Mix™ packaging methodology is a unique process based on fluoropolymer composite substrates for application to microwave multilayer ICs and...

Integrated Software for Electromagnetic Simulation Eagleware Corp. Stone Mountain, GA In the past, most electromagnetic (EM) simulation software has been slow, difficult to use and expensive. =empower= Plus EM software addresses these issues by providing fast, accurate EM simulation. This simulation is completely integrated with traditional circuit simulation, allowing...

A Portable 9 kHz to 2.7 GHz SpectrumAnalyzer IFR Americas Inc. Wichita, KS A new lightweight, portable spectrum analyzer has been developed that covers the 9 kHz to 2.7 GHz frequency spectrum. The model 2398 spectrum analyzer is a fully synthesized instrument that combines ease of use and broad...

SAW IF filters in Mobile Communications Networks Sunder Gopani Sawtek Inc. Orlando, FL As mobile communications networks are making headway in their global expansion, two digital systems are emerging as standards: the Global System for Mobile communications (GSM) and code-division multiple access (CDMA). GSM is implemented predominantly in Europe...

Coupling Behavior between Transmission Lines with Meshed Ground Planes in LTCC-MCMs Multilayer ceramic modules for high speed digital applications use meshed planes between the signal layers for shielding and power supply. Both wave impedances of the signal lines and coupling behavior between different signal layers are influenced by the...

A 1.9 GHz Adaptive Feedforward Power Amplifier A relatively low power feedforward amplifier for 1.9 GHz has been developed to demonstrate the feasibility of the adaptive feedforward linearization technique. The saturated two-tone output power of this amplifier is approximately 4 W. The measured third-order intermodulation is -18 dBc before...

Accurate and Efficient Modeling of Meander-line Polarizers A meander-line polarizer is a passive broadband device used to convert the polarization properties of a wave. When designed properly, the polarizer permits a linear polarized antenna to propagate circular polarization without any significant variations in the pattern performance. Modeling of the...
