Here's an introduction to the application of Field Effect Transistors (FET) as frequency multipliers and harmonic oscillators. With an emphasis on nonlinear techniques, a minimal amount of mathematics, and the proper combination of theory and experimentation, this book helps microwave and millimeter-wave engineers comprehend the fundamental concepts and design rules of frequency multipliers and harmonic oscillators. Design of FET Frequency Multipliers and Harmonic Oscillators focuses on the techniques required to efficiently generate harmonics and emphasizes hardware circuits. It explores the design of narrow and large bandwidth doublers and triplers - both single-ended and balanced configuration. The book shows how to save design time by helping you utilize commercial linear and non-linear software packages, model the MESFET for multiplier operation, and match for wideband stable operation. This reference also explains the association between oscillator theory and frequency multiplier theory in designing harmonic generators and it contains useful information on the non-linear operation of power amplifiers. The important issues when employing MIC or MMIC technologies are discussed to help designers decide on the best approach for a particular circuit. The book contains more than 150 illustrative design examples and over 200 equations.

  • Edmar Camargo

    received his master and Ph.D. degrees from University of São Paulo, Brazil, in 1976 and 1985, respectively. Within this time he took a leave of absence to work at the Centre National d'Études des Telecommunications (CNET) in Lannion France in 1977 and 1982. He was a teacher assistant and research engineer in the same university in Brazil, until 1993 when he emigrated to the U.S. He worked for Hewlett-Packard on mmWave Transceiver design and for Fujitsu Compound Semiconductor Inc., where he took the lead on frequency converter project. From 2000 to 2004 was director of engineering at Fujitsu coordinating the mm-Wave and handset developments. From 2005 to 2009 worked at iTerra Communication, Watkins Johnson Communications on power amplifiers for infrastructure applications and at RF Micro Devices on power amplifiers for handsets. From 2009 to 2012 was a MMIC design consultant, and in 2013 became a Principal engineer at Quinstar Technology in Torrance, California. He retired from QuinStar in 2017 and has since been working as a consultant. Edmar Camargo is a senior member of the IEEE-MTT Society, served on the technical program review committee from 1996 to 2008 and from 2015 to 2017. He also served as a member of the MTT-22 Signal Generation and Frequency Conversion and is currently Chapter of the MTT in Coastal Los Angeles Chapter. He and his wife, Marcia, reside in Lomita, California, have two sons, Marcel and Regis and three granddaughters, Maeve, Chloe and Nia.
