Product Feature A Frequency Discriminator With a Small Footprint Merrimac Industries Inc. West Caldwell, NJ Delay-line frequency discriminators have long been fundamental components in radar warning receivers, instantaneous frequency measurement receivers (IFM) and angle of arrival interferometers. They offer a high performance alternative to I and Q networks in...

Cover Feature Low Cost Millimeter-wave Packaged MMICs United Monolithic Semiconductors S.A.S. Orsay Cedex, France Millimeter-wave technology is being recognized as having potential for emerging markets, such as broadband radio links for cellular base station backhaul networking and automotive safety systems. For such development to occur, however, the requested volumes...

Technical Features LDMOS Linearity and Reliability Laterally diffused metal-oxide-semiconductor (LDMOS) devices have been available as high power, low frequency amplifiers for almost three decades. The original devices had problems with linearity and reliability. More recent developments have improved the device performance and make LDMOS suitable in cellular base station...

Technical Feature Q- and V-band MMIC Low Noise Amplifiers This article describes MMIC low noise amplifiers for millimeter-wave applications using 0.15 µ m pHEMT technology. The design emphasis is on the active device model. The deficiency of conventional device models is identified. A distributed device model has been adapted...

Two orthogonal printed dipole antennas, each with a microstrip via-hole balun...

Tutorial Fibercom Clock Timing - A Review of PLL Solutions Bar-Giora Goldberg Peregrine Semiconductor Corp. San Diego, CA The fiber optics telecommunications market (called here photonics) has experienced huge growth in the last few years. Being a two-level digital transmission format, the requirements for clocking, timing, retiming and sometimes...

Optical networking and its supporting equipment, components and integrated circuits (ICs) are heading toward a market windfall, according to In-Stat/MDR. The high tech market research firm reports that with the geometric growth of the Internet, private IP networks and business-to-business (B2B) e-commerce, the demand for high speed capacity, within...

Isat 903, the latest in a line of advanced communications satellites built for Intelsat by Space Systems/ Loral (SS/L), a subsidiary of Loral Space and Communications, was successfully launched on March 30, 2002. The satellite was sent into space from the Baikonur Cosmodrome in Kazakhstan, aboard an ILS Proton...

According to In-Stat, the Optical Fiber Conference (OFC) held in Anaheim, CA, in March, was much quieter than last year's - a real reflection of the dismal market conditions in the telecom sector right now - and the fact that the tremendous hype surrounding the use of MEMS in...

As evidenced by CeBIT and CITA, Bluetooth solutions continue to make strides. Many products have been first launched in Europe and/or Asia, as many vendors consider the North American market to be behind. However, many companies realize that unless they also make their products available to North America, they...
