The 100 Genesys Design Examples book consolidates relevant knowledge and practical skills that are highly sought-after in the RF industry. This book provides practical hands-on guidance for the practicing engineer or student to quickly acquire the practical understanding of RF circuit design. This is made possible by well-chosen examples created in Keysight Genesys software. , the affordable, powerful synthesis and simulation tool used by more than 5,000 RF and microwave engineers worldwide.Prof. Behagi has thoughtfully incorporated theoretical RF design concepts through familiar MATLAB scripting and equations in the Genesys simulation examples so that readers can use them for learning or as starting points in their designs. Users of Genesys can interactively change design parameters and see results instantly through convenient simulations that have already been set up in these examples. Prof. Behagi's innovative teaching approach breaks the barrier between theory and practice that so often prevents knowledge taught in school from being applied effectively on the job.By judiciously selecting an affordable software, Prof. Behagi has transformed the learning of this difficult subject from being intimidating to enjoyable. It is also personally fulfilling because the reader will acquire skills highly valued in the job market by companies designing RF and microwave products, which range from consumer wireless devices to advanced aerospace and defense systems.

Master's Thesis from the year 2017 in the subject Physics - Technical Physics, grade: 82, Charles Darwin University (School of Engineering and Information Technology), course: Electrical and Electronics Engineering, language: English, abstract: The focus is given on millimeter/micro wave signal generation based on external modulators. The working principle and modulation characteristics of Mach-Zehnder modulators (MZM) are introduced. Literature review is presented on generating millimeter/micro wave signals with 4-, 6-, and 8-times frequency multiplication based on cascaded MZMs or dual-parallel MZMs (DPMZMs). A novel scheme to optically generate a microwave signal with 10-times frequency multiplication is proposed. The proposed scheme is based on two DPMZMs and a polarizer. It does not require electrical phase shifters with specified degrees, which are needed in the conventional 10 times frequency multiplication structure. Simulation is conducted to evaluate the performance of the proposed scheme. When a 1 GHz RF drive signal turns into two DPMZMs with a 35 dB extinction ratio, the proposed 10 times frequency multiplier with an optical sideband suppression ratio (OSSR) higher than 25 dB can be obtained. A 10 GHz mm-wave with an RF spurious suppression ratio (RFSSR) over 16 dB is generated. A frequency quadrupling scheme based on a DPMZM is experimentally demonstrated. With a 3 GHz RF drive signal, an OSSR higher than 8 dB is obtained and a 12 GHz mm-wave is generated with an RFSSR over 11 dB.
