RF Components and Circuits


Book Description

Some basic knowledge of electronics is assumed, but the essential features of RF are fully described, including the important topic of receiver dynamic which is often overlooked in basic textbooks. The theory and circuit descriptions are geared towards genuine design applications rather than the oversimiplifications and skeleton circuits of many college texts. During his career, the late Joe Carr was one of the world's leading writers on electronics and radio, and an authority on the design and use of RF systems. Whether you are looking for a complete self-study course in RF technology, or a concise reference text to dip into, this book has the solution. A complete course in understanding and designing RF circuits Practical design knowhow from a world-class author




RF Circuit Design


Book Description

Summarizes the schemes and technologies in RF circuit design, describes the basic parameters of an RF system and the fundamentals of RF system design, and presents an introduction of the individual RF circuit block design. Forming the backbone of today's mobile and satellite communications networks, radio frequency (RF) components and circuits are incorporated into everything that transmits or receives a radio wave, such as mobile phones, radio, WiFi, and walkie talkies. RF Circuit Design, Second Edition immerses practicing and aspiring industry professionals in the complex world of RF design. Completely restructured and reorganized with new content, end-of-chapter exercises, illustrations, and an appendix, the book presents integral information in three complete sections: Part One explains the different methodologies between RF and digital circuit design and covers voltage and power transportation, impedance matching in narrow-band case and wide-band case, gain of a raw device, measurement, and grounding. It also goes over equipotentiality and current coupling on ground surface, as well as layout and packaging, manufacturability of product design, and radio frequency integrated circuit (RFIC). Part Two includes content on the main parameters and system analysis in RF circuit design, the fundamentals of differential pair and common-mode rejection ratio (CMRR), Balun, and system-on-a-chip (SOC). Part Three covers low-noise amplifier (LNA), power amplifier (PA), voltage-controlled oscillator (VCO), mixers, and tunable filters. RF Circuit Design, Second Edition is an ideal book for engineers and managers who work in RF circuit design and for courses in electrical or electronic engineering.

Tunable RF Circuits Using Iron-Cobalt Ferromagnetic Nanoparticles


Book Description

Modern communication systems are evolving very quickly and tunable Radio Frequency (RF) components are needed to utilize the spectrum more effectively. Recent developments in small size and tunable microwave/RF components are attractive for communication and radar applications for industrial, civilian, and military purposes. Different frequency tuning methods of electrical, mechanical, optical, acoustic, and magnetic are employed for dual frequency of operation. New manufacturing methods are being continuously improved with great interest in additive manufacturing. This PhD thesis work focuses on design and frequency tuning of passive RF circuits using magnetic flux control of ferroic nanomaterials fabricated using additive manufacturing. In particular, the focus of the thesis is using nanoparticles of ferromagnetic Iron-Cobalt (Fe60Co40) and Cobalt ferrites (CoFe2O4) considered for their electromagnetic properties. Compared to ferroelectric materials, the tuning control circuit of ferro/ferrimagnetic materials can be designed without adding parasitic effects. The extracted electromagnetic properties of the realized composites are refraction index of nFeCo=4 and nCoFeO=2, magnetization saturation of MFeCo=198 emu/g and MCoFeO=46.8 emu/g, loss tangents of tanÎþFeCo
