✦ Synopsis

As an undergraduate student taking an upper level wireless circuits course, this book was mandatory and severely disappointed both the class and the instructor. While the book introduces several topics relevant to RF engineering, it goes nowhere in developing central ideas and providing adequate explanations for equations. The logical flow is broken throughout the text, and it would only make sense to someone already familiar to RF engineering. To any engineering students familiar with thin texts covering expansive subject matter, and offering no concrete insight, this book fits perfectly into that category. The one section that developed a little better than the others concerned a review of resonant circuits, however, other texts are available that offer much better coverage.
