Microwave frequency multipliers are very useful and advantageous components in microwave systems, especially, where the generation of high frequency sinusoidal signals is very difficult because of degrading performance of the solid state oscillators with increasing frequency. These components are frequently employed in diverse applications such as commercial wireless communication systems, microwave transmitters and receivers, and military systems. In the following work the basic principles of microwave FET frequency multipliers, specifically concentrated on triplers, are studied presenting theoretical concept and utilizing computerized simulation of piecewise linear FET (PLF) model. The use of PLF model which neglects nonlinear reactances and relies on resistive nonlinearities allows for the theoretical concept and, consequently, the multiplication mechanism in a frequency multiplier to be clearly and easily identified. At the end of this study, after presenting basic considerations on FET frequency multipliers a practical microwave frequency tripler design is presented.

Design and realization of broadband instantaneous frequency discriminator
Pamuk, Gökhan; Yıldırım, Nevzat; Department of Electrical and Electronics Engineering (2010)
n this thesis, RF sections of a multi tier instantaneous frequency measurement (IFM) receiver which can operate in 2 – 18 GHz frequency band is designed, simulated and partially realized. The designed structure uses one coarse tier, three medium tiers and one fine tier for frequency discrimination. A novel reflective phase shifting technique is developed which enables the design of very wideband phase shifters using stepped cascaded transmission lines. Compared to the classical phase shifters using coupled ...
Investigation of multilevel inverters for d-statcom applications
Deniz, Mustafa; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2009)
The most important advantages of Multilevel Inverters are the absence of a coupling transformer for medium voltage applications and low harmonic current content. In this way, relocatable and economical STATCOM systems can be realized. Complex control algorithms and the isolation problems of measurement devices and power supplies are the main challenging parts of this type of application. In this study, the design, realization, and the performance of a Voltage Source Type Cascaded Multilevel Converter Based ...
Down conversion and filtering of microwave signals in optical domain
Selçuk, Gökhun; Şahin, A. Behzat; Department of Electrical and Electronics Engineering (2008)
Processing of microwave signals in electrical domain introduces many difficulties especially when the frequency of the signal is increased beyond several GHz. Electromagnetic interference (EMI) and frequency depended losses can be given as examples to these difficulties. Photonic processing of microwave signals, however, is immune to these problems since optical components such as fiber cables, lasers, optical modulators and photodetectors are both immune to EMI and have wide bandwidths. This thesis deals w...
Analysis of conventional low voltage power line communication methods for automatic meter reading and the classification and experimental verification of noise types for low voltage power line communication network
Danışman, Batuhan; Sevaioğlu, Osman; Department of Electrical and Electronics Engineering (2009)
In this thesis, the conventional low voltage power line communication methods is investigated in the axis of automated meter reading applications and the classification and experimental verification of common noise types for low voltage power line communication network. The investigated system provides the real time transmission of electricity consumption data recorded by electricity meters, initially to a local computer via a low voltage line through a low speed PLC (Power Line Carrier) environment and sub...
Design and implementation of a current source converter based statcom for reactive power compensation
Bilgin, Hazım Faruk; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007)
This research work is devoted to the analysis, design and development of the first medium power Current-Source Converter (CSC) based distribution-type Static Synchronous Compensator (D-STATCOM) with simplest converter topology and coupling transformer connection. The developed CSC-D-STATCOM includes a +/-750kVAr full-bridge CSC employing Selective Harmonic Elimination Method (SHEM), a 250kVAr low-pass input filter at 1kV voltage level, and a Δ/Y connected coupling transformer for connection to medium-voltag...
