This book describes methods to design distributed amplifiers useful for performing circuit functions such as duplexing, paraphrase amplification, phase shifting power splitting and power combiner applications. A CMOS bidirectional distributed amplifier is presented that combines for the first time device-level with circuit-level linearization, suppressing the third-order intermodulation distortion. It is implemented in 0.13um RF CMOS technology for use in highly-linear, low-cost UWB Radio-over-Fiber communication systems.

Software Defined Radio makes wireless communications easier, more efficient, and more reliable. This book bridges the gap between academic research and practical implementation. When beginning a project, practicing engineers, technical managers, and graduate students can save countless hours by considering the concepts presented in these pages. The author covers the myriad options and trade-offs available when selecting an appropriate hardware architecture. As demonstrated here, the choice between hardware- and software-centric architecture can mean the difference between meeting an...

Introduces timed arrays and design approaches to meet the new high performance standards

The author concentrates on any aspect of an antenna array that must be viewed from a time perspective. The first chapters briefly introduce antenna arrays and explain the difference between phased and timed arrays. Since timed arrays are designed for realistic time-varying signals and scenarios, the book also reviews wideband signals, baseband and passband RF signals, polarization and signal bandwidth. Other topics covered include time domain, mutual coupling, wideband elements, and...

This book presents innovative solutions for the implementation of Sigma-Delta Modulation (SDM) based Analog-to-Digital Conversion (ADC), required for the next generation of wireless hand-held terminals. These devices will be based on the so-called multi-standard transceiver chipsets, integrated in nanometer CMOS technologies. One of the most challenging and critical parts in such transceivers is the analog-digital interface, because of the assorted signal bandwidths and dynamic ranges that can be required to handle the A/D conversion for several operation modes.

The book is intended for readers with an
existing base of knowledge regarding the wireless power amplifier (PA), a key
semiconductor component used in all wireless communication products. The PA
influences battery-life, talk-time, cost, and size of wireless communication
devices.

The author presents a complete
pedagogical design methodology for wireless PA design, from specification
stage, to transistor selection, to final circuit design. An electrical
engineer, having read the book, will be able to start with key specifications
and end with a...

RFID technology presents a great potential for creating competitive advantage. By automating and simplifying data collection, it lets users more accurately track assets and monitor key indicators, which in turn gives greater visibility to the operations. However, the benefits received from this technology will be determined by how well it is integrated with the business processes and overall information flow. Because of the fact that the decision to deploy RFID technology in an enterprise is a business decision instead of a technology decision, cost-benefit analysis is a key component of...

• The advantages of adaptivity in implementing...

Where do Canadian content requirements come from? What is the difference between an over-the-top (OTP) service provider and a broadcast distribution undertaking (BDU)? How is broadcast regulation changing in response to the rise of new media? The second edition of Broadcasting Policy in Canada answers these questions by tracing the development of Canada's broadcasting legislation and analysing the roles and responsibilities of the key players in the broadcasting system, particularly those of the Canadian Radio-television and Telecommunications Commission (CRTC).

Revised and...

The book introduces the basic foundations of high mathematics and vector algebra. Then, it explains the basic aspects of classical electrodynamics and electromagnetism. Based on such knowledge readers investigate various radio propagation problems related to guiding structures connecting electronic devices with antenna terminals placed at the different radar systems. It explains the role of antennas in process of transmission of radio signals between the terminals. Finally, it shows the relation between the main operational charactistics of each kind of radar and the corresponding...

The Cold War examines the complex arguments which divided East and West following the end of the Second World War, and analyzes its eight major phases, including:

* the emergence of the Cold War
* Coexistence and Detente
* Glasnost in the late 1980s.

Combining factual overview and background discussion of the key issues such as the nuclear threat and who, if anyone, won the Cold War, with analysis of source material, students will find this a must-have in the study of this major historical event.
