This invaluable resource introduces progressive techniques for the creation of sophisticated reflectionless filter topologies that have identically zero reflection coefficient at all frequencies. Practical implementations are discussed along with their advantages when compared to classical absorptive filters and their benefits in real-world systems such as up/down converters, multiplier chains, broadband amplifiers, analog-to-digital converters, and time-domain applications. This book offers insight into the innovative process of developing reflectionless filters from first principles using both lumped elements and transmission lines. Tools for the creation of reflectionless multiplexers, matched sloped equalizers, and advanced, high-order, and nonplanar topologies are also presented.

This comprehensive resource provides a thorough introduction to the principles of electronic circuits operating in the radio, microwave, and millimeter-wave frequency ranges. The book highlights the fundamental physical laws of classical electromagnetics using a foundation of Maxwell’s equations to give insight into the operating principles of circuit elements of all kinds, from lumped elements to transmission lines, waveguides, optical fibers, and quasi-optical structures. Standard passive system components like filters, splitters, couplers, hybrids, baluns, and antennas are explained to acclimate the reader to considering multiple technological solutions for common design problems. A basic overview of active circuit designs, such as amplifiers, mixers, and multipliers is also provided, along with discussion of the performance characteristics of electronic systems, including noise and linearity. Emphasis is placed on visualization and understanding of how and why electronic circuits of all frequencies are built and operate the way they do. Readers learn how to match an amplifier for optimum noise performance over the broadest bandwidth with the fewest number of elements and how to visualize the coupling of various modes in a mixed waveguide-type structure and avoid resonances due to trapped, higher-order modes. The book provides the tools needed to design and optimize a launcher from microstrip into waveguide, and whether the best characteristics can be achieved by incorporating matching elements in the microstrip section, the waveguide section, or both. Packed with references and examples, readers learn not only how to do the math but what the math means.

For many applications requiring some sort of signal filtering or signal conditioning, the filter requirements are usually approached with a single purpose in mind, which is to maximize both passband signal amplitude and stop band signal attenuation to the load with little to no thought given to what happens to the stop band signal energy. Many conventional filters have very poor impedance matching in the stopband resulting in reflected energy or large return loss. This reflected energy can then cause interactions with adjoining system components which do not in general respond well to spurious reflected energy and can result in degradation of system performance or other unintended consequences. This thesis implements and verifies the design procedure and examines the frequency scaling of a novel passive filter design methodology proposed by Morgan and Boyd which the authors claim results in an easy to realize reflectionless filter which has stopband reflection response superior to conventional passive filters. Following the proposed design methodology, a reflectionless filter was simulated and then realized in a hardware prototype and good agreement observed between simulation and measurement results. To determine the quality of stopband response, the reflectionless filter response was compared to a Butterworth admittance complimentary diplexer designed using accepted techniques. The reflectionless filter showed similar measured stopband response to the diplexer but this was gained with a much simpler design process than was required for the diplexer. To verify the ability of the procedure to scale the design requirements, a filter with a decade wider bandwidth was also designed and the measured response compared to a similarly scaled Butterworth diplexer. For this frequency range of interest, the reflectionless filter exhibited superior stopband rejection when compared to the diplexer. Simulation and measured results were in good agreement for both filters.
