RF Electronics Chapter 1: Introduction Page 4 2022, C. J. Kikkert, James Cook University, ISBN 978-0-6486803-9-0. Computer simulation allows most aspects of the design to be investigated and optimised quickly before any hardware is produced. The modern computer simulation tools are very good and generally allow a correctly functioning design to be produced first time. The main commercial computer simulation systems are: 1) EEsof, which was purchased by Hewlett-Packard, then spun off as Agilent and is now Keysight PathWave Design [5] comprising Advanced System Design (ADS), GoldenGate RFIC Simulator (EMDS), EMPro 3D and other packages. 2) AWR Design Environment software [6] comprising Microwave Office (MWO), Visual Systems Simulator (VSS), Analogue Office, AXIEM, Analyst and other packages. AWR was purchased by National Instruments in 2011 and by Cadence in 2019. 3) Other RF simulation companies are Ansoft and Cadence. Both PathWave and AWRDE perform well, and both allow linear and non-linear circuit analysis, using steady state and time-domain circuit simulation, as well as the more detailed electromagnetic simulation of circuits. The author has used both EEsof EDA and AWR DE for many years. In the author's experience, AWR DE is easier for the students to learn and as a result, AWR DE has been used in the RF electronics course and entry- level electronics and circuit simulation courses at James Cook University. The authors lecture notes for the RF electronics course form the basis of this book. Chapter 2 has deliberately been written to allow it to be used for both advanced RF electronics courses and entry-level courses. Both the Keysight and Cadence AWR software allow the design and simulation of RF IC's. Depending on quantities and manufacturing technology, it can be expensive to manufacture an RF IC. The author encourages the RF designs by the students to be manufactured, to allow the students hardware experience in measurement and fault- finding of RF circuits, as well as providing feedback on their designs. As a result, this book concentrates on using commercial PCB substrates for components like couplers, combiners and filters and using commercial transistors and IC's in active RF designs. The AWR DE project files for each figure in this book are included with this book and are available for download from the AWR web site [6]. For the 2022 edition of this book, AWR DE version V16 has been used for all the simulations. References 1. Kikkert, C. J. "The design of a Ka band satellite beacon receiver".
