Book excerpt: A comprehensive text that covers both receiver and transmitter circuits, reflecting the past decade's developments in solid-state technology. Emphasizes design using practical circuit elements, with basic ideas of electrical noise, resonant impedance-matching circuits, and modulation theory thoroughly explained. Contains the latest techniques in radio frequency power amplifier design, accepted state-of-the-art technology based on bipolar junction transistors, VMOS RF power FETs, high-efficiency techniques, envelope elimination and restoration, envelope feedback, and other newly emerging technologies. Requires a knowledge of complex algebra, Fourier series, and Fourier transforms. Also includes numerous worked-out examples that relate the theory to practical circuit applications, and homework problems keyed to corresponding sections of the text.
