Author Description

"With increasingly low-cost and power-efficient RF electronics demanded by today's wireless communication systems, it is essential to keep up to speed with new developments. This book presents key advances in the field that you need to know about and emerging patterns in large-signal measurement techniques, modeling and nonlinear circuit design theory supported by practical examples. Topics covered include: [bullet] Novel large-signal measurement techniques that have become available with the introduction of nonlinear vector network analyzers (NVNA), such as the LSNA, PNA-X and SWAP [bullet] Direct extraction of device models from large-signal RF dynamic loadlines [bullet] Characterization of memory effects (self-heating, traps) with pulsed RF measurements [bullet] Interactive design of power-efficient amplifiers (PA) and oscillators using ultra-fast multi-harmonic active load-pull [bullet] Volterra and poly-harmonic distortion (X-parameters) behavioral modeling [bullet] Oscillator phase noise theory [bullet] Balancing, modeling and poly-harmonic linearization of broadband RFIC modulators [bullet] Development of a frequency selective predistorter to linearize PAs"-- "This book is concerned with recent advances in the use of nonlinear vector network analyzers (NVNAs) for the characterization, modeling, design, and linearization of nonlinear RF devices and circuits. Wireless has experienced an incredible growth; from cellular phones to wireless local area networks (WLANs), portable radios have become ubiquitous. The trend is to develop RF radios with wider bandwidth and low power dissipation for supporting new broadband services. Of particular importance are the nonlinear RF front-end circuits in radios, which typically dissipate half the handheld power"--
