Free Download RF Antenna Beam Forming: Focusing and Steering in Near and Far Field
English | 2024 | ISBN: 3031670809 | 152 Pages | PDF EPUB (True) | 44 MB
This book is designed for both the scientific audience, research and development engineers and university students. The fundamentals of radio frequency antenna beam forming are explained in this book. The principles of beam focusing and beam steering in near field and far field are visualized with 2D and 3D simulations and compared with measurement results. Besides linear and planar antenna arrays, also conformal arrays, i.e. concave and convex antenna arrays, suitable for certain applications, are investigated and presented. Also related applications of open loop and closed loop beam forming, and massive MIMO, which is one of the break-through technologies for 5G and future 6G and involves an extremely large number of antenna elements for the multi-user beam forming, are discussed in detail. Also covered are large scale antenna arrays as well as thinned antenna arrays with electrically large distances between the antenna elements.

In the arena of Parasitic-Aware Design of CMOS RF Circuits, efforts are aimed at the realization of true single-chip radios with few, if any, off-chip components. Ironically, the on-chip passive components required for RF integration pose miore serious challenges to SOC integration than the active CMOS and BJT devices. This is not surprising since modern digital IC designs are dominated as much, or more, by interconnectg characteristics than by active device properties. In any event, the co-integration of active and passive devices in RFIC design represents a serious design problem and an even more daunting manufacturing challenge. If conventional mixed-signal design techniques are employed, parasitics associated with passive elements (resistors, capacitors, inductors, transformers, pads, etc.) and the package effectively de-tune RF circuits rendering them sub-optimal or virtually useless. Hence, dealing with parasitics in an effective way as part of the design process is an essential emerging methodology in modern SOC design. The parasitic-aware RF circuit synthesis techinques described in this book effectively address this critical problem.

English | PDF | 2005 | 132 Pages | ISBN : 0387238018 | 5.1 MB
This book focuses on high performance radio frequency integrated circuits (RF IC) design in CMOS. 1. Development of radio frequency ICs Wireless communications has been advancing rapidly in the past two decades. Many high performance systems have been developed, such as cellular systems (AMPS, GSM, TDMA, CDMA, W-CDMA, etc. ), GPS system (global po- tioning system) and WLAN (wireless local area network) systems. The rapid growth of VLSI technology in both digital circuits and analog circuits provides benefits for wireless communication systems. Twenty years ago not many p- ple could imagine millions of transistors in a single chip or a complete radio for size of a penny. Now not only complete radios have been put in a single chip, but also more and more functions have been realized by a single chip and at a much lower price. A radio transmits and receives electro-magnetic signals through the air. The signals are usually transmitted on high frequency carriers. For example, a t- ical voice signal requires only 30 Kilohertz bandwidth. When it is transmitted by a FM radio station, it is often carried by a frequency in the range of tens of megahertz to hundreds of megahertz. Usually a radio is categorized by its carrier frequency, such as 900 MHz radio or 5 GHz radio. In general, the higher the carrier frequency, the better the directivity, but the more difficult the radio design.

Free Download Architectures for RF Frequency Synthesizers by Cicero S. Vaucher , Bram Nauta
English | PDF | 2002 | 268 Pages | ISBN : 1402071205 | 14.2 MB
Frequency synthesizers are an essential building block of RF communication products. They can be found in traditional consumer products, in personal communication systems, and in optical communication equipment. Since frequency synthesizers are used in many different applications, different performance aspects may need to be considered in each case. The main body of the text describes a conceptual framework for analyzing the performance of PLL frequency synthesizers, and presents optimization procedures for the different performance aspects. The analysis of the PLL properties is performed with the use of the open-loop bandwidth and phase margin concepts, to enable the influence of higher-order poles to be taken into account from the beginning of the design process. The theoretical system analysis is complemented by descriptions of innovative system and building block architectures, by circuit implementations in bipolar and CMOS technologies, and by measurement results. Architectures for RF Frequency Synthesizers contains basic information for the beginner as well as in-depth knowledge for the experienced designer. It is widely illustrated with practical design examples used in industrial products.
