This updated and expanded second edition reflects the state of earth station design and ground segment architecture. From international telephone network gateways to direct broadcast home receivers, todayas broad range of ground systems and devices require satellite communication engineers and business managers to have a broad and sound understanding of the design and operating principles of earth stations and ground control facilities. This book explores the delivery end of the satellite link and its relationship to delivery of services. Authored by a leading authority in the field, the book provides engineers and managers with the knowledge they need to devise their own approach to implementing and managing earth stations and the overall ground segment. Readers find practical guidance in an array of critical areas, including: preparing requirements, performing preliminary analyses, reviewing hardware designs, managing the introduction of the overall ground segment, and more.It uses a single amplifying element in switch mode with a resonant output circuit to reduce harmonics. ... at microwave frequencies below 5 GHz and with output power of 15W for a push-pull pair of GaAs FET transistors [3, 4]. ... The Doherty Power Amplifier (DPA), developed in the 1930s using vacuum tubes, was introduced in satellites in the ... Figure 9.16 provides the typical circuit diagram of the DPA.
