Approximately 15 years have passed since the first edition of this book, which was
well received by both graduate schools and industry. While the basic principles of
physics and mathematics have not changed, today’s technology has provided us with
huge opportunities to improve the circuit design for linear and nonlinear techniques. In
addition, we felt it would be useful to streamline the book by following the concepts
of systems and their requirements at microwave frequencies, showing the transition
between lumped and distributed elements, and the new exciting devices, particularly
the silicon-germanium transistors and the low-cost BiCMOS technology, which is
competing heavily with gallium arsenide and seems to be winning in many wireless
applications. The cutoff frequencies for modern transistors are in excess of 200 GHz,
with low noise figures and low-voltage operation. Practical oscillators can now be made
up to 70 GHz. For higher power applications gallium arsenide FETs are over 100 W,
and LDMOS devices are also available for frequencies up to 3 GHz. The future looks
very bright for lower noise, higher power, and higher frequencies as the technology
continues to improve at a very rapid pace.
The ultimate handbook on microwave circuit design with CAD. Full of tips and insights from seasoned industry veterans, Microwave Circuit Design offers practical, proven advice on improving the design quality of microwave passive and active circuits-while cutting costs and time. Covering all levels of microwave circuit design from the elementary to the very advanced, the book systematically presents computer-aided methods for linear and nonlinear designs used in the design and manufacture of microwave amplifiers, oscillators, and mixers. Using the newest CAD tools, the book shows how to design transistor and diode circuits, and also details CAD's usefulness in microwave integrated circuit (MIC) and monolithic microwave integrated circuit (MMIC) technology. Applications of nonlinear SPICE programs, now available for microwave CAD, are described. State-of-the-art coverage includes microwave transistors (HEMTs, MODFETs, MESFETs, HBTs, and more), high-power amplifier design, oscillator design including feedback topologies, phase noise and examples, and more. The techniques presented are illustrated with several MMIC designs, including a wideband amplifier, a low-noise amplifier, and an MMIC mixer. This unique, one-stop handbook also features a major case study of an actual anticollision radar transceiver, which is compared in detail against CAD predictions; examples of actual circuit designs with photographs of completed circuits; and tables of design formulae. |
