The Book End Microwave Transistor Amplifiers: Analysis and Design -- Second Edition Guillermo Gonzalez Prentice Hall 506 pages; $86 This second edition presents a unified treatment of the analysis and design of microwave transistor amplifiers using scattering parameter techniques. The design procedures and analysis presented are not limited to...

Ultra-low Noise VCOs Z-Communications Inc. San Diego, CA Currently, there is a demand for lower noise performance and lower cost VCOs, especially in the upcoming personal communications service and digital radio markets. In these applications, both the Colpitts configuration, shown in Figure 1 , and the common-base configuration, shown...

A Surface-mount OCXO for Wireless Applications Reeves-Hoffman Inc. Carlisle, PA The growth of today's electronic communications market is based on increased technological capabilities and making those technologies cost effective. Those same principles led to the development of the surface-mount, oven-controlled crystal oscillator (SMOCXO). The personal communications service (PCS) and...

A High Speed Radio Communications Analyzer Anritsu Wiltron Co. Morgan Hill, CA Speed and flexibility are increasingly crucial requirements of test instruments used by cellular handset manufacturers. The ability to test thousands of handsets -- based on multiple standards -- in as little as an hour is now the...

A Digital Radio LNA Salisbury Engineering Inc. Salisbury, MD The digital radio systems being deployed currently promise increases in spectrum efficiency as well as voice quality. In order to realize this performance outside the laboratory environment, the RF front ends must be more sensitive, linear and robust than their...

Phase-locked Sources for LMDS and MVDS Applications Micro Lambda Inc. Fremont, CA Currently, 28 and 42 GHz mm-wave systems are being offered for wireless local multipoint distribution systems (LMDS) and multipoint video distribution systems (MVDS). Systems operating at 31 GHz have also been proposed for these applications. These systems...

Database Sampling: A Real-world Solution to MMIC Yield Sensitivity Analysis Randall North and David Kennedy Optotek Ltd. Kanata, Ontario, Canada Mike Murphy M/A-COM, Microelectronics Division Lowell, MA In the course of a typical MMIC development and manufacturing program, there are a number of common issues that affect design success...

A Direct 64-QAM Modulator Suitable for MMIC Implementation Surinder Kumar, Abbas Mohammadi and David Klymyshyn Telecommunications Research Labs (TRLabs) and University of Saskatchewan Saskatoon, Saskatchewan, Canada There is considerable worldwide interest in personal communications services (PCS) with wireless data communication. Spectrum allocation for such services has been made and...

Design and Characterization of a Multipurpose PCS Class A Amplifier E. James Crescenzi, Jr. and Walter A. Strifler Watkins-Johnson Co., Microwave Products Group Palo Alto, CA The rapid expansion of personal communications service (PCS) base stations and services has resulted in an increased demand for linear power amplifiers in...
